摘要

Solution properties of ladder-like polymer polyphenylsilsesquioxane (PPS) were studied by measurement of intrinsic viscosity

small angle laser light scattering and gel permeation chromatography. It was found that PPS can be modeled with a wormlike continuous cylinder rather than a wormlike coil. A plot of (M2/[η])1/3 vs. M1/2 was employed in obtaining the persistence length (2λ)-1 and effective hydrodynamic diameter. When MW≤5×105

Mark-Houwink equation is adequate in describing the relationship between MW and [η] with α about unity.This implies that PPS chain is semi-stiff.For GPC experiments

it was shown that univeral calibration can be applied in PPS.When molecular weights of PPS are sufficiently high

their molecular weight ditributions are often very broad.
