HYDROXY-TERMINATED AROMATIC OLIGOMERIC PHOSPHATE AS ADDITIVE FLAME RETARDANT IN POLYCARBONATE RESIN COMPOSITION

摘要

The present application relates to a flame retarded polycarbonate resincomposition which comprises a polycarbonate resin substrate containing aneffective amount (e.g., preferably from about 5 % to about 15 %, by weight ofthe resin substrate) for flame retardancy of a hydroxy-terminated aromaticoligomeric phosphate composition of formula (I), where R is a hydrocarbylgroup derived from an aliphatic or aromatic diol, Ar is an alkyl-substitutedor unsubstituted phenyl group, n is from about 0 to about 10, and thephosphate composition contains a predominant amount of phosphate where nranges from 0 to 1.
