Abstract: A lightly colored thermoplastic composition, suitable for fabrication into panels or sheets, and having high weatherability, comprises:(a) 100 parts by weight of polyolefin elastomer;(b) 15 to 130 parts by weight of crystalline or partially crystalline polyolefin;(c) 30 to 240 parts by weight of chalk and/or siliceous chalk;(d) 0.5 to 20 parts by weight of titanium dioxide; and, optionally,(e) up to 40 parts by weight of bitumen and/or mineral oil; and(f) up to 15 parts by weight of lubricant.

Abstract: A process for preparing a homogeneous liquid mixture consisting essentially of a normally solid polyolefin rubber copolymer of at least two different monoolefinically unsaturated hydrocarbons of 2-8 carbon atoms or of at least two different monoolefinically unsaturated hydrocarbons of 2-8 carbon atoms and at least one copolymerizable unconjugated diene hydrocarbon of 6-16 carbon atoms and at least an equal amount by weight of an extending oil having a viscosity of 50-5000 centistokes and a specific gravity of 0.84 - 0.98, which comprises:A. adding the copolymer to said extending oil at a temperature of 80.degree. - 230.degree.C; andB. admixing the copolymer with the hot extending oil at an agitation speed of 1-500 cm/sec and a shear velocity of 0.5 - 100 sec.sup..sup.-1 for a period of time sufficient to form said homogeneous liquid mixture substantially free of particulate copolymer.
