| abstract |
Compositions based on (1) semi-rigid copolyamides prepared from fatty acid dimers, (2) elastomers comprising sequences compatible or reactive with the copolyamide belonging to the group consisting of: olefinic copolymers comprising carboxyl groups and / or carboxylates, copolyesteramides, polyurethanes, organopolysiloxane and polyurethane block copolymers and copolymers derived from functionalized latexes, and (3) optionally from conventional polyamides.n n n The compositions according to the invention make it possible to obtain molded objects having excellent flexibility and resilience properties, in particular at low temperatures. |
