ABSTRACT The invention provides a core-shell polymer which comprises (a) a core phase having carboxyl groups on surface part of the core and (b) a shell phase which is a glassy polymer containing neither functional groups reactive to the the carboxyl group nor functional groups reactive to the amino group, wherein the toluene-soluble fraction is not higher than 10 % by weight based on the whole core-shell polymer; polyamide resin compositions comprising said core-shell polymer; and molded articles produced by molding said compositions. Impact strength of the resin composition or its molded articles was improved by using the core-shell polymer.
