Patent ID: 7235597

Claim:
A styrenic thermoplastic resin composition, without polycarbonate or polyphenylene ether, comprising a) 100 weight parts of a base resin, by weight of the base resin: i) 10 to 50 weight percent(wt. %) of a rubber-modified styrene-containing graft copolymer comprising 30 to 65 weight parts of a styrene compound and 10 to 30 weight parts of an acryl compound on 10 to 60 weight parts of a rubber, which the styrene compound is selected from the group consisting of a styrene, α-methylstyrene, nuclear substitution styrene, and a mixture thereof, and the acryl compound is selected from the group consisting of an acrylonitrile, methylmethacrylate, butylacrylate, and a mixture thereof, and the rubber is selected from the group consisting of polybutadiene, styrene-butadiene copolymer, polyisoprene, butadiene-isoprene copolymer, and a mixture thereof; ii) 5 to 20 wt. % of phenol novolac resin; iii) 30 to 70 wt. % of a styrene-containing copolymer comprising 50 to 90 wt % of a compound selected from the group consisting of styrene, α-methylstyrene, nuclear substitution styrene, and a mixture thereof and 10 to 50 wt % of a compound selected from the group consisting of acrylonitrile, methylmethacrylate, butylacrylate, and a mixture thereof; and iv) 10 to 40 wt. % of a thermoplastic polyurethane resin, and b) 5 to 20 weight parts of a phosphorous compound represented by the following Chemical Formula 3, which is not substituted with halogen:
