ABSTRACT OF THE DISCLOSURE An adhesive resin composition is obtained by mixing at least one member (C) selected from the group consisting of unsaturated carboxylic acids and the derivatives thereof, a free-radical initiator (D), and a mixture consisting of a crystalline polyolefin resin (A) and an amorphous or low crystalline olefin copolymer of ethylene and an a-olefin (B), to obtain a precursor mixture, melt-kneading the precursor mixture in the first half of an extruder having at least one side feeder, to obtain a modified precursor mixture, and feeding a crystalline polyolefin resin (E) from the side feeder of the extruder and mixing the resin ( E ) with the modified precursor mixture. The adhesive resin composition has good extrudability and exhibits high adhesive property to polar materials such as polar polymeric materials and the like.
