Abstract

A thermoplastic elastomer composition, containing a) 5 to 99 wt % of a block copolymer, which is constructed of hard blocks (A) made of vinyl aromatic monomers and one or more random soft blocks (B) of non-hydrogenated or hydrogenated block copolymer materials made of dienes and vinyl aromatic monomers, b) 1 to 95 wt % of a plasticizer having a higher polarity than white oil and a lower polarity than dinonyl adipate, c) 0 to 50 wt % of a polyolefin, and d) 0 to 60 wt % of additives, has advantageous properties in regard to processability.
