Abstract
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 .alpha.-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.
