ABSTRACT:
A compound comprising a blend of polypropylene with the reaction of a functionalized polypropylene and polyether amine in which the polyether amine is grafted into the functionalized polypropylene in a customary mixing apparatus is disclosed. The blend may include an elastomer such as EP rubber and/or a filler such as glass. A process for producing the reaction product of the functionalized polypropylene and the polyether amine by melting with polypropylene in a customary mixing apparatus is also disclosed. Blends of the present invention are advantageously useful to prepare paintable automotive body parts. A polyether monoamine that contains from about 36 to about 44 ethylene units and from about 1 to about 6 propylene units, and processes and blends using same.
