The present invention relates to a flame retardant thermoplastic resin composition that contains a phenol resin derivative having good char formability, regardless of the base resin. A flame retardant thermoplastic resin composition according to the present invention comprises (A) 100 parts by weight of a thermoplastic resin as a base resin, (B) about 0.1&#x2dc;100 parts by weight of a phenol resin derivative, and (C) about 0.1&#x2dc;50 parts by weight of a phosphorous compound or a mixture of phosphorous compounds.

Flame retardant thermoplastic resin composition

The present invention relates to a flame retardant thermoplastic resin composition that contains a polyphenylene ether resin and a phenol resin derivative, both of them having good char formability, regardless of the base resin. A flame retardant thermoplastic resin composition according to the present invention comprises (A) 100 parts by weight of a thermoplastic resin as a base resin, (B) about 0.1&#x2dc;100 parts by weight of polyphenylene ether, (C) about 0.1&#x2dc;100 parts by weight of a phenol resin derivative, and (D) about 0.1&#x2dc;50 parts by weight of a phosphorous compound or a mixture of phosphorous compounds. The thermoplastic resin composition may contain up to 5.0 parts by weight of an anti-dripping agent based on 100 parts by weight of the base resin.
