Abstract
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 (preferably, EPM) or unsaturated (preferably, EPDM) olefin copolymer rubber. These graft copolymer compositions are well-balanced with respect to impact strength and stiffness at high ductility levels. The compositions, which may be admixed with one or more additives such as inorganic fillers in an amount, for example, of up to about 80 parts additive per 100 parts of the graft copolymer and rubber component, are rigid thermoplastics useful as stand-alone structural materials.
