摘要

Since the reactivity of Me

SiCl

（Ⅰ） and ■（Ⅱ） are very different. it is difficult to cocondensate the above two monomers with sodium in general Wurtz reaction. We have proposed a modified method to prepare copolymer containing permethylpolysilane segments and cyclodisilazane units by reaction of （Ⅱ）with Na at first

then adding （Ⅰ） into the mixture to proceed with further reaction.The obtained copolysilanes are pale yellow elastic substance and soluble in common solvents. The amounts of N in the copolymers are influenced by the operating conditions of the synthetic method. The resultant products were characterized by IR

NMR

and elementary analysis. The highest molecular weight determined by gel permeation chromatography is 60000.
