The present paper describes structural characteristics of crosslinked copolymers of acryl-dicyclohexylurea (A-DCU) and methacryl-dicyclohexylurea (MA-DCU) with ethylene glycole dimethacrylate (EDMA). Both copolymers decompose when heated at temperatures between 180-250°C under the separation cyclohexylisocyanate (C

The comparison was also made between structural characteristics of crosslinked nanoporous copolymers of poly(A-CHA-co-EDMA) and poly(MA-CHA-co-EDMA) and nonporous crosslinked model compounds poly(A-CHA-co-EDMA) and poly(MA-CHA-co-EDMA).
