PURPOSE: A composition having improved impact resistance, heat resistance, and thermal aging resistance, obtained by blending a polysulfone resin with a resin composition consisting of a graft polymer and a copolymer having the same constitutio- nal monomers respectively. n CONSTITUTION: 90W10wt%, preferably 70W15wt% polysulfone resin is blended with 10W90wt%, preferably 30W85wt% resin composition comprising a graft polymer obtained by grafting at least two selected from the group consisting of an aromatic vinyl monomer, vinyl cyanide monomer, and other polymerizable monomer onto a rubber copolymer consisting essentially of ethylene-propylene and a copolymer consisting of the monomers. The graft polymer has preferably 95W40wt% monomer and 5W60wt% rubber copolymer, and the copolymer has preferably an intrinsic viscosity (dimethylformamide at 30°C) of 0.5W1.3. n COPYRIGHT: (C)1982,JPO&Japio |
