Abstract

PURPOSE: The polycondensation reaction between a specific phenoxaphosphine derivative and an aromatic amine gives the titled polymer of high heat resistance and high flame retardancy.
CONSTITUTION: The titled polymer that is composed of recurring units of formula I (R is tetravalent aromatic group; X is imino group or oxygen atom) and preferably has 0.1W1.5dl/g reduced viscosity. The polymer is obtained by the polycondensation reaction between (A) a phenoxaphosphine derivative of formula II (Z is hydroxyl, halogen atom) such as 2,8-dicarboxy-10-phenylphenoxaphosphine-10-oxide and (B) a compound of formula III (R is tetravalent aromatic group; Y is amino, hydroxyl) such as 3,3'-diaminobenzidine tetrahydrochloride.
USE: Heat-resistant coating, additive for imparting heat resistance to plastics.
