Abstract

Traditionally, most polyphosphazenes have been prepared by the thermal ring-opening and macromolecular substitution route. However, this approach allows only minimal control of the molecular weight and generates broad polydispersities. A new ambient temperature condensation synthesis method overcomes these drawbacks. The method involves the living cationic-induced polymerization of Me3SiN double bond PCl3 with trace amounts of PCl5 and yields polymers with well defined molecular weights and narrow polydispersities. The method can also be used to synthesize both block and star-branched copolymers.
