Abstract
A compound comprising a blend of polypropylene with the reaction of a functionalized polypropylene and polyether amine in which the polyetheramine 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.
Claims73
A composition comprising polyolefin, a polyolefin vulcanizate, and the reaction product of a functionalized polypropylene and a polyether amine.
A composition useful as a material for making paintable automotive body parts, comprising:
- polyolefin;
- polyolefin vulcanizate;
- and
- the reaction product of functionalized polyolefin and a polyether amine.
A process for preparing a composition useful for making molded automotive body parts, comprising:
