Abstract
Abstract 1. A thermoplastic fluorine-containing resin blend composition comprising (a) from 5 to 95% by weight of a thermoplastic fluorine-containing resin, and (b) from 95 to 5% by weight of at least one modified ethylene polymer selected from the group consisting of the following components (i) and (ii). (i) A modified ethylene polymer obtained by subjecting an ethylene polymer and an alkyl acrylate to graft reaction conditions, wherein the total alkyl acrylate content including the alkyl acrylate which has been previously contained is from 5 to 70% by weight based on the weight of the modified ethylene polymer; (ii) A modified ethylene polymer obtained by subjecting an ethylene polymer having a crystallinity of from 4 to 50% and vinyl acetate to graft reaction conditions, wherein the total vinyl acetate content including the vinyl acetate which has been previously contained is from 5 to 70% by weight based on the weight of the modified ethylene polymer and the boiling xylene insoluble content is 10% by weight or less based on the weight of the modified ethylene polymer.
