Abstract

PURPOSE:To thermally regulate the structure of a crystalline polyorganophosphazene, by heating or cooling a crystalline polyorganophosphazene with a specified temperature range. CONSTITUTION:A crystalline polyorganophosphazene of the general formula: [(OR)2PN]n (wherein R is a 1-30C alkyl, an aryl or an amino group, and n is an integer of 20-20,000) is heated or cooled within a temperature range from room temperature to 180 deg.C. In this way, the crystal structure of said polyorganophosphazene is changed to another through a cycle of alpha-delta-gamma-alpha. According to this process, changes between the alpha form and the gamma form can be reversibly performed.
