ABSTRACT:
A thermoplastic elastomer composition consisting essentially of (A) 2 to 50% by weight of a polybutadiene having a 1,2-addition unit content of 70% or more, (B) 20 to 90% by weight of an olefinic rubber and (C) 5 to 60% by weight of a polyolefin resin, 30 to 95% by weight of the total polymer components, up to 90% by weight of said polybutadiene and up to 90% by weight of said olefinic rubber being soluble in Tetralin when the composition is heated at 210.degree. C for 3 hours in Tetralin under reflux. Said composition is excellent in mechanical strength, weather resistance, oil resistance, heat stability and processability and has a small permanent set.
