Production of polyorganophosphazenes having desired molecular weights

摘要

A method for producing a polyorganophosphazene, such as, for example, poly[di(carboxylatophenoxy)phosphazenel], from polydichlorophosphazene. The polydichlorophosphazene is reacted with at least one nucleophilic reagent at a defined molar ratio of the at least one nucleophilic reagent to the polydichlorophosphazene. Such process results in the production of a polyorganophosphazene having a molecular weight within a desired range.
