Title:
FIRE RETARDANT THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2000038501
Kind Code:
A
Abstract:

To improve stress crack resistance and thermal stability by compounding a thermoplastic polycarbonate resin, a graft copolymer, a vinyl- based copolymer, a phosphorus-based compound and a fluorinated polyolefin resin.

Use is made of a thermoplastic polycarbonate resin containing no halogens. A graft copolymer is obtained by graft polymerizing a monomer mixture comprising one component such as styrene and the other component such as acrylonitrile onto a polymer which is a mixture such as a butadiene rubber with a glass transition temperature of -10°C or less. A vinyl copolymer is obtained by copolymerizing styrene and the like and acrylonitrile and the like. A phosphorus-based compound contains a compound of formula I or II. A fluorinated polyolefin-based resin has an average particle diameter of 0.05-1,000 μm and a density of 2.0-2.3 g/cm3. In formulae I and II, R1, R2, R4 and R5 are each a 6-20C aryl group or the like; R3 is a bisphenol A derivative; M is 0.1-3; R is an alkyl group; and N is 0-3.
