“METHOD FOR MANUFACTURING A POLYESTER COMPOSITION HAVING IMPROVED IMPACT PROPERTIES”

摘要

The invention relates to a method for manufacturing a thermoplastic composition including: a polyester resin (c); a mixture including a copolymer (a) of an a-olefin and of a monomer having an ethylenic unsaturation and an epoxy function  as well as a core-shell compound (b); characterized in that said method includes: a first step of manufacturing the mixture of (a) and (b) by extrusion at a temperature at which the copolymer (a) is in the molten state and at a maximum temperature of 60 to 180°C; a second step of manufacturing the thermoplastic composition by extrusion or by mixing the polyester resin (c) with the mixture of (a) and (b) produced in the first step.
