Abstract: A graft copolymer comprising a polyamide to which is grafted a glycidyl group-containing acrylate copolymer. The graft copolymer can be prepared by dispersing in an organic solvent a polyamide and a material which will react with the polyamide to form the graft copolymer of the polyamide and the acrylate copolymer and reacting the polyamide and the material so as to form said graft copolymer. The graft copolymer can exhibit improved toughness and reduced friability and can be used to form molded articles and in coating compositions, especially powder coating compositions. The coatings can exhibit transparency, reduced brittleness and increased chip resistance. The powder coatings can further exhibit high gloss and smoothness due to superior flow characteristics thereby enabling thinner coatings to be used that provide acceptable appearance.
