Abstract: This paper describes the synthesis and polymerization of acrylic monomers which contain dicyclohexylurea (DCU) as a pendant group. Crosslinked copolymers of these monomers with ethylene glycol dimethacrylate (EDMA) were prepared under the standard free radical initiated polymerization with dibenzoyl-peroxide (Bz2O2) as initiator, in butanone at 70 °C, up to high conversion. It was found that copolymers, regardless of the ratio of comonomers in the feed. thermally decompose by the two-step mechanism under the separation of almost quantitative yield of cyclohexylisocyanate, in the temperature range from 180 °C to 250 °C. The residues left by the removal of isocyanate were thermally stable crosslinked molecularly imprinted copolymers of acryl-cyclohexylamide (A-CHA) with EDMA, which decompose by a one-step mechanism between 300 °C and 450 °C. In order to compare the properties of nanoporous crosslinked copolymers of A-CHA with EDMA with those of nonporous poly(A-CHA-co-EDMA) of the same molar composition, nonporous copolymers were prepared by the polymerization of A-CHA with EDMA under the conditions described above
