Preparing thermoplastic composition e.g. polyester resin and mixture of copolymer and monomer and epoxy and core-shell, comprises preparing mixture of copolymer and core-shell by extrusion, and mixing polyester resin with the mixture

摘要

Preparing thermoplastic composition comprising polyester resin (c), and a mixture comprising a copolymer (a) of alpha -olefin and a monomer bearing an ethylene unsaturation and epoxy group and composed of core-shell (b), comprises a first step of manufacturing the mixture (a) and (b) by extrusion at a temperature at which the copolymer (a) is in the molten state and a maximum temperature of 60-180[deg] C; and second step of manufacturing the thermoplastic composition by extrusion or by mixing the polyester resin (c) with the mixture (a) and (b) obtained in the previous step. An independent claim is included for the composition obtained by the process.
