ABSTRACT:
The present invention relates to new block copolymers of chemically modified polyolefins and thermoplastic polyurethanes, copolyesters or copolyamides a method for the preparation of said block copolymers and their use for compatibilizing blends of polar and non-polar thermoplastic elastomers. The block copolymers according to the present invention can further be used for promoting the adhesion of thermoplastic elastomers onto various polar engineering resins.
