Abstract

In the reported experimental program, a new class of high molecular weight polyphosphazenes, which contain direct-phosphorus-carbon bonds, has been prepared by the thermal polymerization of partially alkylated cyclic phosphazenes, N//3P//3Cl//5R, and 1,1-N//3P//3Cl//4R//2. Molecular structures of monomers used and polymers obtained are detailed. The discussion is summarized under headings - replacement of the residual chlorine in monomers; polymerization conditions; influence of alkyl groups on chain length; effects of the alkyl groups on general physical properties.
