Abstract
The invention thus provides a core-shell polymer comprising a core phase which is rubbery polymer and a shell phase which is a glassy polymer with an unsaturated dicarboxylic acid or its mono-alkyl ester as a constituent thereof, wherein the toluene-soluble fraction of the core-shell polymer accounts for not more than 10% by weight. It also provides polyamide resin compositions comprising said core-shell polymer and molded articles produced by molding said compositions. The resin compositions and molded articles which comprises the core-shell polymer as an impact modifier have good features, especially a high impact strength at temperature ranging from room temperature to -30.degree.
