Abstract
The mixture of the invention contains, for 100 parts in weight of (A)+(B): (A) 10 to 90 parts in weight of at least one non-nanostructured olefinic thermoplastic polymer; (B) 90 to 10 parts in weight of a formulation of at least one elastomer having unsaturated double bonds and capable of reacting with a cross-linking or vulcanization agent, said formulation containing a crosslinking or vulcanization system of said elastomer(s), at least one plasticizer, and the standard additives present in elastomer formulations; (C) up to 100 parts in weight, relative to (A)+(B), of at least one copolymer grafted with polyamide blocks, said copolymer comprising a polyolefin trunk and at least 1.3 polyamide grafts on said trunk in average, and having a nanostructured organization, wherein said grafts are attached to the trunk by the rest of an unsaturated monomer (X) having a function capable of reacting with a polyamide with an amine end; and rest of said unsaturated monomer (X) being attached on the trunk by grafting or copolymerization from its double bond thereof, and wherein (A) and (B) in the mixture can already have been combined together by the crosslinking or vulcanization dynamic method…
