ABSTRACT:
Compositions prepared by blending asphalt and reject polypropylene which contains a mixture of atactic and isotactic polypropylene and includes inorganic salts and other residues from the polypropylene manufacturing process have outstanding wetting characteristics and surprisingly high adhesive strengths. These compositions can be employed for bonding polyolefins, metals, woods, papers and a wide variety of other materials and can also be molded for use in other applications. Such compositions are superior to blends of asphalt and essentially pure atactic or isotactic polypropylene.
