Abstract
A thermoplastic elastomer exhibiting scarce tendency of depositing gummy crust around the extrusion die upon extrusion molding articles therefrom and a superior oil-resistance, which comprises (A) a crystalline polyolefin resin and (B) a cross-linked rubber component produced by a specific melt-kneading technique and which has a certain high level of gel content, a high oil-resistance and a certain reduced rate of deposition of gummy crust on the extrusion die.
