STUDIES ON THE POLYSILANE CONSISTING CYCLODISILAZANE UNITS IN THE MAIN CHAIN

Received Date: 20 January 1988

Since the reactivity of Me2SiCl2(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,UV,NMR and elementary analysis.The highest molecular weight determined by get permeation chromatography is 60000.
