Abstract
In the case where a polyamide is blended with a specific partially crosslinked graft-modified polyolefin elastomer obtained by dynamically heat-treating a blend of a peroxide-crosslinking olefin copolymer rubber and an olefinic plastic with an unsaturated carboxylic acid or derivative thereof, an unsaturated epoxy monomer or an unsaturated hydroxy monomer in the presence of an organic peroxide, if the graft-modified polyolefin plastomer occupies a major portion, a composition excellent in the oil resistance, the mechanical strength and the resistance against heat aging is obtained and if the polyamide occupies a major portion, a composition excellent in the impact resistance, the rigidity and the tensile strength is obtained.
