摘要
Disclosed is a polyolefin composition comprising (A) an irradiated, normally solid, high molecular weight, amorphous to predominantly crystalline olefin polymer material and (B) a non-irradiated propylene polymer material or a mixture thereof with an olefin copolymer rubber. The polyolefin composition of this invention also provides improved retention of embossing definition commonly referred to as grain retention, when the composition is extruded and embossed, with or without subsequently thermoforming.
