    Heterogeneous polymer systems. II. Characterization of graft copolymers of styrene on polyethyl acrylate (1963)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 7 (1963), S. 59-69

    Notes: The isolation of two graft copolymers of styrene on polyethyl acrylate from the ungrafted homopolymers by solvent extraction procedures is discussed. For the grafts and their corresponding mixtures ηsp/c versus c plots were determined, and no anomalies were observed. Qualitative data on the solubilities and phase properties of the grafts are given. Torsional modulus-temperature curves are shown for graft copolymer and the individual homopolymers.

    Differential thermal analysis of silicones (1961)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Polymer Science 55 (1961), S. 419-422 
    Details
    ISSN: 0022-3832
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology , Physics
    Notes: Differential thermal analysis has been applied to several silicone polymers and compounds with the use of oxidative conditions. The model compounds gave melting points corresponding to literature values. However, volatilization gave a broad endotherm much lower than extrapolated boiling points. The order, in oxidative resistance, was dimethyl silicone oil, silphenylene, methyl phenyl silicone oil.

    Bis(imidazolato)-metal polymersThis work was supported by the Aeronautical Systems Division, Air Force Systems Command, U. S. Air Force. (1964)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A: General Papers 2 (1964), S. 1839-1845

    Notes: The reaction of imidazole and the sulfates of Cu(II), Zn(II), and Co(II) in aqueous NaHCO3 gave products whose analysis corresponded to two imidazole residues per metal atom. The products were insoluble in common organic solvents and had very high melting points. Thermogravimetric analyses revealed that the Co- and Zn-containing materials had unusually high thermal stability, as no loss in weight could be detected below 500-575°C. when heated in nitrogen. The properties led to their formulation as metal coordinate polymers. The electrical resistivity of the products was in excess of 1015 ohm-cm. at 140°C.
