Summary: | One aspect of the invention relates to an acrylate-vinyl aromatic-unsaturated nitrile graft copolymer. The acrylate-vinyl aromatic-unsaturated nitrile graft copolymer can include: a double layered rubbery polymer comprising an inner core layer of alkylacrylate-vinyl aromatic copolymer and an outer core layer of alkylacrylate polymer; and a vinyl aromatic-unsaturated nitrile copolymer shell layer grafted onto the double layered rubbery polymer. Another aspect of the invention relates to a weatherable thermoplastic resin composition including the foregoing acrylate-vinyl aromatic-unsaturated nitrile graft copolymer.
Sous l'un de ses aspects, l'invention concerne un copolymère greffé acrylate-vinyl aromatique-nitrile insaturé. Le copolymère greffé acrylate-vinyl aromatique-nitrile insaturé peut inclure un polymère caoutchouteux à deux couches comportant une couche de coer interne de copolymère alkylacrylate-vinyl aromatique et une couche de coer externe de polymère d'acrylate d'alkyle ; une couche d'écorce de copolymère vinyl aromatique-nitrile insaturé greffée sur le polymère caoutchouteux à deux couches. Sous un autre aspect, l'invention concerne une composition de résine thermoplastique résistante aux intempéries incluant le copolymère greffé acrylate-vinyl aromatique-nitrile insaturé précité. |
