ABSTRACT:
Polyimido-ester compounds having the formula RO--C(O)--R.sub.1 --C(O)--OR are disclosed wherein R is an alkylene N-dicarboximido radical containing cycloolefinic unsaturation and R.sub.1 is the divalent residue of an unsaturated polycarboxylic acid such as fumaric, itaconic, aconitic, mesaconic, or glutaconic acid. These compounds are blended with unsaturated resins such as unsaturated polyester resin or vinyl ester resin, and polymerizable unsaturated monomers such as styrene to provide thermosettable resin compositions which can be cured to provide castings or laminates with improved resistance to thermal aging.
