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.

Abstract: The present invention provides an adhesive composition and a hot-melt adhesive that are suitably used for bonding a polyolefin resin substrate and a polar material, and that are capable of low-temperature adhesion. The adhesive composition comprises an acid-modified polypropylene (A), an unfunctionalized polypropylene (B), and a polyethylene (C), and has a melting point of 70 to 140° C.
