  • RESIN COMPOSITION
    Publication number: 20220340748
    Abstract: This invention provides a modified polyolefin resin composition that contains a large amount of an unsaturated carboxylic acid or an anhydride thereof, and that can inhibit an increase in fluidity after graft modification due to little influence of a reaction residue, wherein the resin composition when used as a compatibilizer for reinforced fiber plastics provides a molded article with excellent mechanical properties such as bending strength and impact resistance.
