Document Type and Number:
Japanese Patent JP4057235
Kind Code:
B2
Abstract:
A process for producing a polyorganophosphazene from a polyhalophosphazene. The polyhalophosphazene is reacted with a metal salt of an alkyl ester of hydroxybenzoic acid wherein the metal salt of the alkyl ester of hydroxybenzoic acid is contained in a homogeneous melt solution. The reaction of the polyhalophosphazene with the metal salt of an alkyl ester of hydroxybenzoic acid produces a macromolecular substituted polymer, which is reacted with a base to hydrolyze the polymer and produce the desired polyorganophosphazene product.
