Abstract

Thermoplastic adhesive compositions such as hot melts containing conventional components are improved considerably by the inclusion of acid or acid derivative grafted polyolefins particularly acrylic acid-grafted polypropylene, polyethylene and/or ethylene-propylene polymer substances. Alternatively, novel adhesive compositions are prepared in which the polyolefin constituent is entirely a grafted polyolefin.
