A process for preparing a crosslinked polymer comprises reacting a polycyanoacetic functional monomer or polymer with a poly .alpha.,.beta.-unsaturated ester in the presence of a catalytically effective amount of a metallic catalyst. A crosslinked polymer produced by this process is also described.

Cyanoacetic ester system

Cross-linking agents are produced by reacting an ester of a di- or poly-carboxylic acid with a molar excess of ammonium hydroxide, thereby forming a di- or polyamide, which in turn is then methylolated and etherified with a lower alkanol. These products are cross-linkers for resins such as alkyds, oil-free polyesters, acrylic which can be either acid or hydroxy functional, phenolics, epoxies or melamines.
