摘要

The limiting viscosity number [η] and translational diffusion coefficient D of polyphenylsilsesquioxane (PPSQ) and their dependence on molecular weight Mw were studied by static and dynamic light scattering and viscometry techniques. NMR measurement was also performed to investigate PPSQ's structure. Results show that PPSQ molecules are not rigid rods and do not have fully regular ladder structure but with branches and uncondensed hydroxy groups

and their extensibility decreases with the increase of molecular weight.
