Abstract
The invention relates to a thermoplastic elastomer composition comprising a mixture of a. 5-50 wt. % of a block copolymer type thermoplastic polyurethane elastomer (TPE-U) b. 5-50 of a block copolymer type thermoplastic co-polyester elastomer (TPE-C), and c. 10-60 wt. % of a thermoplastic styrenic block copolymer (TPE-S), wherein the wt. % is based on the total content of the elastomer composition. The elastomer composition might be efficiently connected with polar polymers so that corresponding polymer articles are formed.
