The subject invention relates to a thermoplastic elastomer composition that contains a dynamically vulcanized thermoplastic elastomer (a) on the basis of a polypropylene polymer and an at least partly dynamically vulcanized rubber, a thermoplastic polyester block copolymer (b) and a compatibilizer (c). The rubber is preferably an EPDM or EPM copolymer. The thermoplastic polyester block copolymer is preferably a polyether ester block copolymer. The thermoplastic elastomer composition according to the invention for instance contains 20-80 parts (a), 80-20 parts (b), and 1-40 parts (c), the sum of the parts (a+b+c) being 100. The thermoplastic elastomer composition according to the invention also relates to molded articles that contain the thermoplastic elastomer composition. |
