A thermoplastic resin composition comprising a thermoplastic resin (A) and graft copolymer particles (B). The thermoplastic resin composition contains the graft copolymer particles (B) in an amount of 1 to 11 parts by weight based on 100 parts by weight of the thermoplastic rein (A). The graft copolymer particle (B) comprises a hollow rubber portion and a graft chain and a volumetric proportion of hollow part in the hollow rubber portion is 1 to 70 % by volume on the basis of the hollow rubber portion. The hollow part in the graft copolymer particle functions to further improve impact resistance.
Cette composition à base de résine thermoplastique comporte 100 parties par poids d'une résine thermoplastique (A) et de 1 à 11 parties par poids de particules de copolymère greffé (B), comprenant chacune une partie creuse en caoutchouc et une chaîne de greffage. La valeur du volume relatif des parties creuses dans la partie creuse en caoutchouc est comprise entre 1 et 70 % en volume. La résistance aux chocs est encore accrue par l'existence des parties creuses dans les particules de copolymère greffé.
