GRAFT COPOLYMER COMPOSITIONS |
摘要 |
Disclosed are compositions of (a) about from 60 to 95% of a graft copolymer comprising a styrene polymer grafted onto a propylene polymer material at a styrene polymer graft level of about 10-65%, and exhibiting a morphology in which the grafted styrene polymer is a dispersed phase and the propylene polymer material is the matrix phase, and (b) about from 40 to 5% of a rubber component comprising a monoalkenyl aromatic hydrocarbon-conjugated diene block copolymer, alone or in combination with a saturated or unsaturated olefin copolymer rubber. The compositions are rigid thermoplastics useful as stand-alone structural materials. |
