Abstract
The invention relates to a copolymer having polyamide PA blocks and polyether PE blocks, in which PA is of diamine.diacid X.Y type; X, the number of carbons of the diamine, is within the range from 6 to 14, and Y, the number of carbons of the diacid, is within the range from 6 to 18. The invention also relates to the use of the said copolymer in a process of direct adhesion between two TPE materials for increasing the peel strength between these materials.
