Title:
難燃性ポリカーボネート樹脂組成物および成形品
Document Type and Number:
Japanese Patent JP4778601
Kind Code:
B2
Abstract:
Provided is a non-halogen, flame-retardant polycarbonate resin composition that comprises a resin mixture of (A) from 60 to 99 % by mass of a polycarbonate resin and (B) from 1 to 40 % by mass of a polycarbonate copolymer having phosphorus atoms in its main chain, and contains (C) from 0.02 to 5 parts by mass, relative to 100 parts by mass of the resin mixture, of an anti-dripping agent. Also provided are moldings of the composition. The polycarbonate copolymer (B) that has phosphorus atoms in its main chain is typically a polycarbonate copolymer of which the repetitive structural units contain an aromatic organophosphate component. The resin moldings have good impact resistance, good heat resistance and high stiffness intrinsic to polycarbonate resin. Not depositing on the wall of molds, the melt of the resin composition is well flowable and is stably molded into high-quality moldings having good appearance, and its long-run workability is good.
