POLYMER STRUCTURES AND PROPERTIES

Abstract

Investigations relating to dilute solutions of polymers comprised: a theoretical treatment of Rayleigh scattering to include both intramolecular and intermolecular optical interference effects; the temperature dependence of the second virial coefficient for polystyrene in cyclohexane; the intrinsic viscosity-molecular weight relation for poly-(vinyl acetate) in butanone; and design and construction of a precision light scattering photometer. The melt viscosity-molecular weight relation at 218C for monodisperse polystyrene prepared anionically was found to be identical with that for ordinary fractions. Poly-(vinyl acetate), prepared by an emulsion polymerization in the presence of a protein, yielded an insoluble component containing bound protein. Preliminary stress-strain measurements on cross-linked swollen polyethylene gave only equivocal evidence for specific solvent effects on the unperturbed randomflight dimensions of the polymer chains.
