Patent ID: 6913804

Claim:
A composition comprising, per 100 parts by weight: 95 to 85 parts of a thermoplastic polymer (D), 5 to 15 parts of (A)+(B) wherein (A) is a copolymer comprising polyamide blocks and polyether blocks, wherein the polyamide blocks and polyether blocks of copolymer (A) do not contain at least one ionic functional group, (B) is a polymer or an oligomer which comprises, in its chain, at least one ionic functional group and is selected from the group consisting of: polyamides, copolymers comprising polyamide blocks and polyether blocks, thermoplastic polyesters or polyesteramides, copolymers comprising polyester blocks and polyether blocks, polyethers, and polyurethanes, and (D) is selected from the group consisting of polyolefins, polyamides, fluoropolymers, saturated polyesters, polycarbonate, styrene resins, polymethylmethacrylate, thermoplastic polyurethanes, copolymers comprising polyamide blocks, copolymers comprising polyester blocks and polyether blocks, polyvinylchloride, copolymers of ethylene and of vinyl alcohol and polyketones, and wherein polymer (D), copolymer (A) and polymer (B) are not the same.
