摘要：
Poly(silylenemethylene)s with the repeating Si-C backbone units are well-examined carbosilane polymers. We synthesized two poly(silylenemethylene)s, poly(diphenyl-silylenemethylene) (PDPhSM) and poly(methyl phenyl-silylene-methylene) (PMPhSM). These two polymers have different physical, thermal and mechanical properties. This work discusses the structures and dynamics of the Si-C backbone and phenyl side groups of these two polymers by C-13 and Si-29 solid-state NMR and reveals relationships between the thermal and mechanical properties and between structures and dynamics of the Si-C backbone and the side chains.
