## CPC

- C08G 69/00: Macromolecular compounds obtained by reactions forming a carboxylic amide link in the main chain of the macromolecule (products obtained from isocyanates or isothiocyanates C08G18/00; polyamide-imides C08G73/14)
- C08G: MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS

## Abstract

A thermosettable polyaminoester composition useful as a plastic, coating, resin modifier, and elastomer is provided. The thermosettable polyaminoester is formed by reacting one or more acrylic or methacrylic terminated polyalkylene maleate or fumarate oligomers with one or more polyamines and optionally with one or more alpha, beta-ethylenically unsaturated monomers. The composition is especially useful in the RIM process.

## Claims

### Claim 1

A thermosetting polyaminoester resin composition comprising the reaction product of one or more acrylic or methacrylic terminated polyalkylene maleate or fumarate oligomers of the formula ##STR8## wherein n is 2 to 10,
R is H or CH.sub.3,
R' and R" are --H, --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 Cl, --CH.sub.2 Br, --C.sub.6 H.sub.5 (phenyl, --CH.sub.2 OCOCH.dbd.CH.sub.2, --CH.sub.2 OCOC(CH.sub.3).dbd.CH.sub.2, --CH.sub.2 OCH.sub.2 .dbd.CH.sub.2, --CH.sub.2 OC.sub.6 H.sub.5, --CH.sub.2 OC.sub.4 H.sub.9, or
R' together with R" form --C.sub.4 H.sub.8 -(cyclic), and R"' is H or --CHR'CHR"OH, with one or more polyamines.

### Claim 2 (depends on 1)

Composition of claim 1 further comprising the reaction product of said oligomers and said polyamines with one or more alpha, beta-ethylenically unsaturated monomers.

### Claim 6 (depends on 1, 2)

Composition of claims 1 or 2 wherein the oligomer is a methacrylic terminated polyethylene maleate.

### Claim 7 (depends on 2)

Composition of claim 2 wherein said monomers are selected from styrene or methyl methacrylate.
