Abstract:
A method of manufacturing a thermoplastic composition comprising: melt blending (A) a polyetherpolyamide block copolymer with (C) a copolymer of styrene and either maleic anhydride or maleic acid wherein the molar ratio of styrene to maleic acid or maleic anhydride lies in the range from 1/1 to 4/1, and optionally (D) at least one grafted or copolymerized comparibilizer selected from the group consisting of (a) a polyolefin, (b) a copolymer of an olefin with (meth)acrylate and (c) a copolymer an olefin with vinyl acetate, said (a), (b) and (c) being grafted or copolymerized with at least one of an unsaturated carboxylic acid, an unsaturated carboxylic acid anhydride and an unsaturated epoxide, to produce a melt blended mixture; pelletizing the melt blended mixture; andthen blending (B) a polyolefin with the resultant pelletized mixture.
