    Notes: The free-radical polymerization of vinyl fluoride has been studied with the use of organic peroxide and azo initiators over the temperature range of 60-150°C. and at pressures of 75-1000 atm. Molecular weights of the polymers by osmotic pressure or radiotracer techniques were found to vary over the range of 45,000 to 180,000 depending on polymerization conditions employed. Stabilized high molecular weight polyvinyl fluoride may be compression-molded into tough, high-impact strength bars, or the unstabilized material may be cast into films from solvents such as dimethylformamide. The films, which may be cold drawn, are tough, brilliantly clear, and have tensile strengths near 8000 lb./in.2 They are also extremely resistant to weathering, maintaining clarity and cold drawability even after ten years' exposure in Florida.

    The thermal decomposition of dicumyl peroxide in polyethylene glycol and polypropylene glycol (1963)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The changes in solvent resistance and solution viscosity of polyethylene glycol and polypropylene glycol after heating with dicumyl peroxide at 140°C. are consistent with crosslinking of the former and degradation of the latter. Analytical work showed that in both cases all of the peroxide decomposed could be accounted for acetophenone and cumyl alcohol. In the case of polyethylene glycol, crosslinking results from abstraction of secondary hydrogen atoms and dimerization of the resulting radicals; in the case of polypropylene glycol abstraction of tertiary hydrogen atoms leads to radicals which break down by scission at a C—O bond to give a ketone and a more stable radical. This latter process proceeds with an efficiency of unity.

    Thermosetting vinyl and acrylic copolymers (1963)

    Notes: Infrared spectra indicate that carboxyl-substituted acrylic copolymers react appreci8bly with a butylated melamine-formaldehyde resin when heated at 120°C. for 30 min., but under these conditions acid catalysis is needed before epoxy- or amido-substituted copolymers will crosslink with the melamine-formaldehyde resin. Two methods have been used to synthesize hydroxyl-substituted acrylic copolymers. First, a glycidyl methacrylate copolymer was reacted with diethplamine. Second, an acrylic acid copolymer was heated under reflux with butylene oxide in the presence of a basic catalyst. This second method was used to esterify a vinyl toluene-acrylic acid-acrylamide copolymer which was subsequently treated with paraformaldehyde. The resulting hydroxy-methylolamido copolymer intercondensed when heated at 120°C. for 30 min., somewhat as did the hydroxy copolymer with melamine-formaldehyde resin blends.

    Polymerization of N-vinylcarbazole with ziegler-type catalyst systemsThis work was sponsored by International Business Machines Corporation, San Jose, California. (1963)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A: General Papers 1 (1963), S. 125-138 
    Details
    ISSN: 0449-2951

    Notes: The polymerization of N-vinylcarbazole with the TiCl4-Al(i-Bu)3, TiCl4-AlEt3, TiCl3-Al(i-Bu)3, and the TiCl4-n-BuLi systems was studied. It was found that N-vinylcarbazole undergoes a very facile cationic polymerization with TiCl4, or TiCl3, and that catalyst complexes which contain a low metal alkyl/transition metal halide ratio promote a very rapid cationic polymerization. When the catalyst components are mixed in the presence of monomer, considerable cationic polymerization due to the transition metal halide alone takes place before the reaction between the titanium halide and metal alkyl is complete. Experiments with catalyst components mixed in the absence of monomer have shown that the rate of the reaction is markedly dependent on the ratio of the catalyst components and that each system studied had a characteristic ratio at which the catalytic activity suffered a marked drop. With TiCl3-Al(i-Bu)3 this drop occurred at an Al/Ti ratio of 0.8, with TiCl4-Al(i-Bu)3 at an Al/Ti ratio of 3, and with TiCl4-n-BuLi at a Li/Ti ratio of 1.5. This was interpreted as indicating that at these ratios the surface of the titanium halide becomes completely modified by the metal alkyl so that no N-vinylcarbazole-titanium halide interaction could take place. The per cent reduction of TiCl4 to lower valence states was studied with the n-BuLi-TiCl4 system as a function of the Li/Ti ratio and it was found that the maximum per cent reduction takes place at a Li/Ti ratio of 2. The per cent reduction rapidly decreased to zero at higher Li/Ti ratios. The polymers of N-vinylcarbazole formed with Ziegler-type catalyst systems were examined by x-ray diffraction, by their appearance under a polarizing microscope, by infrared spectroscopy, and by nuclear magnetic resonance. These measurements indicated that only amorphous, atactic polymers were formed.

    Notes: A system is described which uses photosynthesis to regenerate oxygen from exhaled carbon dioxide in sealed cabins in the absence of gravity. Design considerations as to choice of algal strain, illumination, nutrients and gas-exchange methods are discussed. Details are given of such an apparatus, of laboratory size, used to evaluate selected semipermeable gas-exchange membranes. Data is presented and extrapolated to estimate size and weight of a possible manned space system.
