Abstract:
Thermoplastic compositions comprising:40 to 97 percent by weight of a thermoplastic polymer (M) forming a matrix, the thermoplastic polymer (M) being selected from the group consisting of fluoro polymers, polycarbonate, styrene resins, PMMA, thermoplastic polyurethanes (TPU), copolymers containing polyester blocks and polyether blocks, polycarbonate-polyester alloys, polyketones, PVC and ethylene-vinyl alcohol copolymers (EVOH), 60 to 3 percent by weight of (B) comprising: either an ethylene-alkyl (meth)acrylate copolymer (B1), the alkyl having at least 8 carbon atoms, which copolymer (B1) further carries a functional group selected from the group consisting of carboxylic acids, carboxylic acid derivatives other than the ester functional group of the acrylate portion of the copolymer (B1), acid chlorides, isocyanates, oxazolines, epoxides, amines and hydroxides, or a blend of an ethylene-alkyl (meth)acrylate copolymer (B2), the alkyl having at least 8 carbon atoms, which copolymer (B2) does not carry a functional group selected from the group consisting of carboxylic acids, carboxylic acid derivatives other than the ester functional group of the acrylate portion of the copolymer (B2), acid chlorides, isocyanates, oxazolines, epoxides, amines and hydroxides, and of an impact modifier which carries a functional group selected from the group consisting of carboxylic acids and their derivatives, acid chlorides, isocyanates, oxazolines, epoxides, amines and hydroxides; wherein the percentages by weight of (M) and (B) are based on the total weight of each composition.
