    Notes: Polyfunctional alcohols, acyclic, cyclic, and heterocyclic imines, and organotin oxides have been studied as crosslinking agents for chlorosulfonated polyethylene. Mechanisms for the crosslinking reactions involving the sulfonyl chloride moiety have been proposed. Differences in curing activity have been correlated with structural modifications of the curing agents consistent with classical chemical reactions for nonpolymeric systems. Of the curing systems examined, the polyols provide nontoxic, low cost, safe-processing formulations offering excellent physical properties which have found use in practical commercial applications.

    Steric effects in the preparation and saponification of some fibrous cellulose estersPaper presented at the 142nd National Meeting of the American Chemical Society, Division of Cellulose, Wood, and Fiber Chemistry, Atlantic City, New Jersey, September 9-14, 1962. (1964)

    Notes: Two reaction paths which can be followed when an acid chloride reacts with an alcohol are discussed. The role of pyridine as solvent and catalyst in this reaction is described. The importance of inductive and resonance effects and the size and arrangement of groups near the carbonyl are emphasized. The heterogeneous preparations of seven cellulose partial esters, the phenylacetate, benzoate, trimethylacetate, triphenylacetate, β,β,β-triphenylpropionate, α-(4-biphenylyl)phenylacetate, and mesitoate are described. Pronounced interference with esterification is noted only in the preparation of the triphenylacetate. Steric hindrance and a poor ability to ionize are considered to be responsible for this result. Outstanding resistance to saponification, thought to be the result of steric hindrance and a reduced tendency to ionize, is reported for three of the cellulose esters, the triphenylacetate, the β,β,β-triphenylpropionate, and the mesitoate.

    Notes: Isotherms have been obtained for the absorption of water by proteins and polyamides and by simple amides closely related to the repeat chemical unit of the polymers. The differential heat of absorption of water at zero water content has also been determined for these substances, from isosteres and from heats of mixing. In addition the nature of the hydrogen bonding of water to these compounds has been investigated by infrared spectroscopic methods. The large differences found between the heats of absorption by the polymers and the simple model compounds are discussed.

    Certain fine structure and thermal properties of benzhydrylated cotton cellulose (1967)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The present paper describes the results of a preliminary study of certain physical and thermal properties of benzhydrylated cotton yarns. The 200-yd. lengths of 7/2 yarn consisting of purified mercerized cellulose were reacted in a special reactor to various degrees of substitution from DS 0.31 to DS 1.22 with benzhydryl bromide in a mixture of equal volumes of 2,6-lutidine and dimethylformamide. The products were examined for tensile strength at break, which decreased only slightly with substitution; ultimate elongation, which was relatively uniform at 60-70% of the control yarn; and tenacity, which decreased with substitution largely due to added weight. The energy of rupture remained relatively constant at about 50% above the control. Tensile stiffness decreased progressively with substitution to about 25% of the control. Density decreased 10-11% with substitution. Crystallinity of the cellulose largely disappeared with substitutions above DS 1, and the lattice of benzhydryl cellulose began to appear. Stiffness, elastic recovery and work recovery were measured on 5-in. specimens of the yarn in an oven while they were subjected to repeated extension to about 1-2% and relaxed as the temperature was raised twice to 200°C. and lowered. During the heating phase of the first cycle the yarn underwent considerable heat adaptation. However, during the cooling phase and during both heating and cooling phases of the second cycle, the yarns showed generally favorable behavior. Attempts are made to interpret the results in terms of molecular modifications.

    Bis-type modifiers in polymerization. II. Comparison of effectiveness of various compounds in emulsion butadiene and bulk styrene polymerizationsContribution Number 206 from the Research Laboratory of The Goodyear Tire & Rubber Co., jointly with the University of Illinois.

    Notes: The present paper describes the preparation and evaluation of the effectiveness as modifiers of a number of compounds of bis-type structure - principally aryl disulfides - in bulk styrene and emulsion butadiene polymerizations. This work endeavors to explore some of the objectives described in the first paper of this series, and deals primarily with attempts to gain quantitative information on the effect of the nature and location of substituting groups with respect to the dissociating bond. The compounds examined include both those containing reactive groups attached and those lacking such groups. A number of the preparations are now compounds. Evaluations in 50°C. bulk styrene were carried out with the objective of eliminating the complications of the diffusion factor always present in emulsion systems. Generally speaking, the correlation between effectiveness in bulk styrene and 50°C. emulsion butadiene was quite good, though there were exceptions. It was found that the modifier activity of many compounds in emulsion butadiene could be enhanced by predispersing them in the aqueous phase - presumably a result of minimizing the importance of diffusion rate. Some of the modifiers were also tested in a low temperature butadiene emulsion system. Aryl disulfides continue to offer the most promise from the standpoint of combining the features of attaining high transfer constants and ease of incorporating desired reactive groups. Some compounds had adequate activity in emulsion butadiene polymerizations for use as practical modifiers. However, it has not yet been established that these compounds cleave to give one-half the molecule on each end of the butadiene polymer chain, as has been done for styrene polymers.

    Effect of RCA cleaning on the surface chemistry of glass and polysilicon films as studied by ToF-SIMS and XPS (1998)

    Notes: The surface chemistry of an alkaline-earth boroaluminosilicate glass is changed by contact with chemical solutions. The present study shows that RCA cleaning creates a silica-rich surface on the glass. This altered surface can be removed by hydrofluoric acid etching. During the RCA cleaning process, glass components can be transferred to a polysilicon film placed in the same alkaline solution. The acidic solution in turn removes most of the contamination from the polysilicon. © 1998 John Wiley & Sons, Ltd.

    Notes: This paper describes a comprehensive experimental investigation of the fire performance of nailed gusset connections between large glue-laminated timber members. Both plywood and steel gusset plates were investigated with a range of loaded and unloaded test methods. The principal conclusions are that unprotected gussets have poor fire performance, but that a layer of solid wood or gypsum plasterboard will provide at least one hour of fire protection to typical joints.

    Inorganic coordination polymers. XII. Chromium(III) tris(phosphinates) (1973)

    Notes: Cohesive films of a series of chromium(III) tris(phosphinates)[Cr(OPRR′O)(OPR″-R‴O)(OPR*R**O)]y in which the side groups on the phosphorus are alkyl, phenyl, and/or hydrogen groups have been prepared by reaction casting or by hot pressing. The preparative reaction appears to involve conversion of an aquahydroxo or hydroxo chromium(III) bis(phosphinate) to an intermediate hydroxo bis(phosphinate) containing coordinated phosphinic acid followed by an intrachain reaction leading to the tris(phosphinate). Tensile strengths of the chromium(III) tris(phosphinates) range from 100 to 5600 psi, elongations from less than 1 to 100%. Thermogravimetric data indicate that major decomposition occurs at temperatures from 200 to 435°C in air and from 410 to 510°C in nitrogen. Infrared spectra and physical properties are interpreted to support a structure for the chromium(III) tris(phosphinates) which is based on linear, triple-bridged chains. The presence of octyl or other long alkyl side groups on the phosphorus improves the physical properties, presumably by internal plasticization, but leads to decreased thermal stability.
