| Abstract: | Molecular-weight parameters of new silane homo- and copolymers were analyzed. For all polymers, theM
w values are close ((6.0–8.6)·104), the curves of molecular weight distribution are unimodal, andM
w/M
n=2−2.5. Cyclic fragments or those containing the −C=C− groups make the major contribution to the polysilane chain rigidity.
