Abstract
(EN)
Provided is a multilayer-structured polymer particle having excellent long-term thermal stability in a matrix resin (base resin), and an excellent dispersibility and impact resistance in order to reduce defects in a molded body including a film. The multilayer-structured polymer particle has: an inner layer containing a cross-linked rubber (I); and an outer layer containing a thermoplastic resin (II) which is grafted with the inner layer, wherein the ratio [V2/V1] of the mass (V2) of the outer layer to the mass (V1) of the inner layer is 0.3-0.8, and the glass transition temperature of the outer layer is 80-120 °C.
(FR)
L'invention fournit des particules de polymère à structure multicouche qui tout en présentant une excellente stabilité thermique sur le long terme dans une résine matrice (résine de base), se révèle excellente en termes de propriétés de dispersion et de résistance aux chocs, afin de réduire les défauts dans un corps moulé contenant un film. Plus précisément, l'invention concerne des particules de polymère à structure multicouche qui possèdent une couche interne contenant un caoutchouc réticulé (I), et une couche externe contenant une résine thermoplastique (II) greffée à ladite couche interne. Le rapport [V2/V1] de la masse (V2) de ladite couche externe vis-à-vis de la masse (V1) de ladite couche interne, est compris entre 0,3 et 0,8. La température de transition vitreuse de ladite couche externe est comprise entre 80 et 120°C.
