Abstract: The invention relates to a non-cross-linked copolymer foam with polyamide blocks and polyether blocks, wherein: the polyamide blocks of the copolymer have an average molar mass of from 200 to 1,500 g/mol; the polyether blocks of the copolymer have an average molar mass of from 800 to 2,500 g/mol; and the weight ratio of the polyamide blocks to the polyether blocks of the copolymer is from 0.1 to 0.9. The invention also relates to a method for manufacturing said foam and items manufactured from said foam.

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.

Abstract: A method for impregnating strands or strips of natural fibers, using the following successive steps: i) the impregnation of the strands or strips by immersion in a bath containing a fine aqueous polymer dispersion; followed by ii) the drying of the strands or strips using a heating system, with the progressive elimination of the water and the gradual melting of the polymer, and the coating of the strands or strips and the molten polymer incorporated into the core of the strands or strips as a binder between the fibers; iii) optionally, the forming of the treated strands or strips into their final shape; and iv) the cooling of the treated strands or strips. The aqueous polymer dispersion comprises at least one semi-crystalline or amorphous polymer and, in the case of an amorphous polymer, has a Tg varying between 50° C. and 175° C.
