Abstract

PURPOSE: The titled ealstomer, useful for parts in automobiles, e.g. a body panel, having improved thermal aging resistance, and prepared by incorporating a specific crosslinked rubber component which is lightly crosslinked by the dynamic heat treatment and a polyolefin resin component in a specific composition.
CONSTITUTION: (A) A lightly crosslinked rubber component which is obtained by mixing (a) ethylene-propylene-polyene copolymer rubber with (b) ethylene-propylene copolymer rubber containing no polyene component and (c) an organic peroxide at a weight ratio between the components (a) and (b) of 10:90W90:10, and dynamically heat-treating the resultant mixture is incorporated and kneaded with (B) a polyolefin component at a weight ratio between the rubber component [components (a) and (b)] and the resin component [component (B)] of about 30:70W90:10 in a Banbury mixer, etc. under heating, and then passed through rolls into a sheet, which is pelletized by a cutter. Thus, the aimed elastomer is obtained.
