| 摘要 |
The present invention relates to a thermoplastic resin composition with excellent long-term heat-aging properties, comprising:(I) 10 to 45% by weight of a rubber-modified thermoplastic resin obtained by graft polymerizing at least one monomer selected from the group consisting of aromatic vinyl compounds, vinyl cyanide compounds and other vinyl monomers copolymerizable therewith in the presence of a rubber-like polymer;(II) 5 to 30% by weight of a thermoplastic resin obtained by copolymerizing the monomers comprising an aromatic vinyl compound, a vinyl cyanide compound and optionally other vinyl monomer copolymerizable therewith; and(III) 50 to 70% by weight of a polycarbonate resin,the content of the vinyl cyanide compound in the whole produced composition being 3 to 12% by weight.
