CA 2286649
A thermoplastic resin composition comprising (A) a thermoplastic resin and (B) graft copolymer particles each having a hollow rubber moiety (in which the volume of the cavity is 1 to 70 %) and a graft chain in an A-to-B weight ratio in the range of 2/98 to 90/10. The impact resistance is further improved by the effect of the cavities in the graft copolymer particles.
L'invention concerne une composition de résine thermoplastique comprenant (A) une résine thermoplastique et (B) des particules de copolymère greffé présentant chacune une fraction d'élastomère creux (le volume de cavité allant de 1 % à 70 %) et une chaîne greffée selon un rapport de poids A-à-B compris dans la fourchette 2/98-90/10. On améliore encore la résistance aux chocs de par l'effet que produisent les cavités dans les particules de copolymère greffé.
