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

摘要

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