Abstract

PURPOSE: A highly heat-resistant, flame-retardant polyester having phenoxyphosphine rings.
CONSTITUTION: A polyester, reduced viscosity about 0.2W2dl/g, comprising repeating units represented by formula I, wherein R is a group selected from formulas IIWXIII. The above polyester has a m.p. about 288W355°C, does not decompose even at about 400°C, exhibits sufficient heat resistance and is self-extinguishing and flame-retardant. Said polyester is prepared by polycondensing (interfacial polymerization is preferred) an aromatic diol with 2,8-dihalogenoformyl-10-phenylphenoxaphosphine 10-oxide represented by formula IX, wherein X is a halogen.
