    Notes: Moisture present in epoxy anhyride composites may hydrolyze the anhydride and cause major changes in the mechanical and chemical properties of the final composite. Heat distortion data and infrared spectroscopy are used to analyze the changes caused by the presence of the moisture. As the concentraton of water is increased, there is a decrease in the heat distortion or gass transition temperature. The decrease is due to a change in the crosslinking network and is caused by the reduction of the functonality of the epoxy group for acid as compared to the anhydride. Where rigid specifications must be met it is essential that the moisture level in the fillers, resins, etc. be kept constant.

    Thermoplastic properties of polyacrolein and its acetalsPresented in part at the 148th Meeting of the American Chemical Society, Chicago, September 1964. (1965)
    New York : Wiley-Blackwell

    Notes: Free-radical polyacrolein is an essentially pure head-to-tail vinyl polymer which results in its being a poly- 1,5-dicarbonyl compound. The proximity of these carbonyl groups results in a partial cyclization (laddering) in the polymer or in its derivatives, which in turn has about the same effect on modulus as adding methyl groups to the backbone chain of a polyacrylate or pendant phenyl groups to the backbone chain of polyethylene. Above a viscosity-average molecular weight of about 200,000, respectable high polymer properties are attained, comparable to those of poly(methyl methacrylate) or polystyrene with higher heat deflection temperatures. Although thermal properties are sufficient to withstand boiling water, actual water and solvent resistances are marginal to poor.

    Radiation chemistry of iodine-octamethylcyclotetrasiloxane solutions (1964)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A: General Papers 2 (1964), S. 3781-3790 
    Details

    Notes: Post-irradiation polymerization of γ-ray-irradiated liquid octamethylcyclotetrasiloxane containing a small amount of iodine was observed. The effect occurs at room temperature without an additional stimulus, and we conclude that it results from catalysis by HI3, i.e., a complex of HI + I2. Hydrogen triiodide is produced when iodine-octamethylcyclotetrasiloxane solutions are irradiated with γ-rays from Co60. HI3 is a good rearrangement catalyst for siloxane bonds. The dose is critical; short irradiations do not produce enough HI, while longer irradiations consume most of the I2. The triiodide complex dissociates at temperatures equal to or greater than 60°C.; thus, the polymerization stops as the temperature is raised, but contrary to usual post-irradiation polymerization processes, resumes when the sample cools. Pure irradiated octamethylcyclotetrasiloxane polymerizes upon the addition of iodine. We assume that the irradiation produces silicon-hydrogen bonds which react with iodine yielding the catalyst HI3. In all systems the HI3 was identified spectrophotometrically. However, its role in the polymerization was established directly when it was determined that an unirradiated iodine-octamethylcyclotetrasiloxane solution polymerized upon the addition of HI.
