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.
Claims51
A reaction product of a functionalized polypropylene and a polyetheramine.
A reaction product of maleated polypropylene and polyetheramine prepared from ethylene oxide, propylene oxide, or combination thereof.
A process comprising:
- contacting polyetheramine with functionalized polypropylene under conditions effective to form a reaction product of the functionalized polypropylene and polyetheramine.
A process comprising:
- contacting maleated polypropylene and polyetheramine in an extruder at a temperature of from about 175.degree. C. to about 300.degree. C. under conditions effective to form a reaction product of the maleated polypropylene and the polyetheramine.
A composition comprising:
- polypropylene;
- an elastomer;
- and the reaction product of functionalized polypropylene and polyetheramine, wherein the polyetheramine has a molecular weight of from about 150 to about 12,000.
