Abstract
AbstractFractions of some polyphenylsilasesquioxane (1) samples were investigated by light scattering, flow birefringence, and viscometry. The correlation between intrinsic viscosity, radii of gyration, and second virial coefficient on the one hand and molecular weight on the other indicate branching of the polymer molecules. An analysis of viscosity and birefringence data suggests differences in the degree of perfection of the ladderlike structure.
