摘要:
A flame retardant resin composition which has high flame retardancy, excellent heat resistance and physical properties and is obtained from a plant-derived raw material and a molded article thereof. The flame retardant resin composition comprises: (A) 100 parts by weight of a polylactic acid and/or a lactic acid copolymer (component A); (B) 1 to 100 parts by weight of a styrene-based resin and/or a polycarbonate resin (component B); and (C) 1 to 100 parts by weight of an organic phosphorus compound represented by the following formula (1) (component C).
(wherein X 1 and X 2 are the same or different and each an aromatic substituted alkyl group represented by the following formula (2))
(wherein AL is a branched or linear aliphatic hydrocarbon group having 1 to 5 carbon atoms, Ar is a phenyl group, naphthyl group or anthryl group all of which may have a substituent. n is an integer of 1 to 3, and Ar can be bonded to any carbon atom contained in AL.)
