Abstract
A compound comprising a blend of polypropylene with the reaction product of a functionalized polypropylene and polyether amine in which the polyether amine is grafted onto the functionalized polypropylene in a customary mixing apparatus is disclosed. 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.

A process, comprising compounding component (a) that includes polypropylene with component (b) that includes the reaction product of (i) a polyetheramine and (ii) a polypropylene that has been reacted with a compound selected from the group consisting of:
- an olefinically unsaturated carboxylic acid;
- an olenfinically unsaturated carboxylic acid anhydride;
- and an olenfinically unsaturated carboxylic acid ester, at a temperature of from about 175.degree. C. to about 300.degree. C.
A process, comprising compounding component (a) that includes polypropylene with component (b) that includes the reaction product of (i) a polyetheramine and (ii) a maleated polypropylene, at a temperature of from about 175.degree. C. to about 300.degree. C.
A process, comprising compounding in a mixing apparatus:
- (a) polypropylene;
- and
- (b) the reaction product of (i) a polyetheramine and (ii) a functionalized polypropylene produced by reacting polypropylene with a compound selected from the group consisting of an olefinically unsaturated carboxylic acid, an olefinically unsaturated carboxylic acid anhydride, and an olefinically unsaturated carboxylic acid ester;
- to produce a paintable thermoplastic resin.
A process, comprising compounding in a mixing apparatus:
- (a) polypropylene;
- and
