  • Rubber-modified thermoplastic resin composition
    Patent number: 4814388
    Abstract: A rubber-modified thermoplastic resin composition obtained by copolymerizing an aromatic vinyl compound and optionally other monomers copolymerizable therewith in the presence of an ethylene-.alpha.-olefin type rubbery polymer having a molecular weight distribution parameter Mw/Mn of 1.2 to 4.5. Said polymer preferably has Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 40 or less. Said composition is excellent not only in weather resistance and impact resistance but also in rigidity, surface gloss and molded product appearance.
