Abstract
The invention relates to a polycarbonate resin composition having good durability even in high-moisture atmospheres, and to a flame-retardant polycarbonate resin composition in which the flame retardants adheres little to molds while the resin composition is molded. The polycarbonate resin composition comprises (A) a polycarbonate resin and (B) an inorganic filler, and contains (C) an arylphosphine and optionally (D) a flame retardant.
Claims9
A polycarbonate resin composition comprising (A) from 50 to 99.9% by weight of a polycarbonate resin and (B) from 0.1 to 50% by weight of an inorganic filler selected from the group consisting of talc, mica, kaolin, diatomaceous earth, calcium carbonate, calcium sulfate, barium sulfate, glass fibers, carbon fibers, and potassium titanate, and containing (C) from 0.01 to 1 part by weight, relative to 100 parts by weight of the total of(A) and (B), of an arylphosphine of formula (1):
- P−(X)3 (1)
- wherein X represents a hydrocarbon group, and at least one X is an optionally-substituted aryl group having from 6 to 18 carbon atoms.
