Abstract: The present paper describes the synthesis of monomers N-methacryl-N, N'-dicyclohexylurea (MA-DCU) and N-methacryl-N,N'-diisopropylurea (MA-DiPrU) and their polymerization with ethylene glycol dimethacrylate (EDMA). Polymerization were carried out in butanone by using dibenzoyl-peroxide (Bz 2O2) up to high conversion. All prepared copolymers are insoluble in common organic solvent. Crosslinked copolymers decompose thermally at temperatures from 180 °C to 450 °C under the separation of cyclohexylisocyanate (C6H11NCO) or isopropylisocyanate (C3H7NCO) at temperature between 180 °C and 250 °C. Residues after the removal of isocyanate are thermally stable nanoporous crosslinked copolymers of methacryl-cyclohexylamide (MA-CHA) or methacryl-isopropylamide (MA-iPrA) with EDMA, which decompose by a one-step mechanism between 280 °C and 450 °C. Nonporous model copolymers of MA-CHA and MA-iPrA with EDMA were also prepared in order to compare their properties with the properties of corresponding nanoporous copolymers
