Abstract
A polyolefin composition containing elastomers (plasticizers), crystalline polypropylene, modified by mixing with polybutene-1 and a coupling agent and a bicyclic dicarboxyl acid salt nucleating agent and/or a lubricant which comprises an unsaturated fatty acid ester which acts as a surface modifier in a molded article is described. The composition is adapted to be used with pigments to make finished molded articles which have an appearance of paint covered by a clear coat and which are scratch resistant and have good low temperature (−30° C.) impact properties.
