STUDY ON POLYPHENYLSILSESQUIOXANE'S SHAPE IN DILUTE SOLUTION

Received Date: 30 October 1986

Based on relations between the limiting viscosity number, the translational diffusion coefficient and the molecular weight, the shape of polyphenylsilsesquioxane (PPSQ) in dilute solution was simulated with different models. It is found that the oblate ellipsoid of revolution and free-draining random coil are two suitable models, showing that PPSQ is a polymer with rigid chains, and its shape is closer to sphere due to chain branching rather than flexibility.
