PREPARATION OF NANOPOROUS CROSSLINKED POLY(METHACRYL-N-CYCLOHEXYLAMIDE-CO-ETHYLENE GLYCOL DIMETHACRYLATE) BY THERMAL DEGRADATION OF POLY(METHACRYL-N, N'-DICYCLOHEXYLUREA-CO-ETHYLENE GLYCOL DIMETHACRYLATE)

Copolymers of methacryl-dicyclohexylurea (MA-DCU) with ethylene glycol dimethacrylate (EDMA) at monomer-to-monomer ratios in the feed: 0.3/0.7 ; 0.5/0.5 ; 0.7/0.3, 0.8/0.2 were prepared in butanone in the presence of 2% of dibenzoyl peroxide at 700C for 48 hours. Copolymers regardless of the ratio of comonomers in the feed decompose thermally at 200-2500C under the separation of cyclohexylisocyanate (C6H11NCO). Residues after the removal of C6H11NCO are thermally stable nanoporous crosslinked copolymers of methacryl-cyclohexylamide (MA-CHA) with EDMA which decompose by a one-step mechanism between 300 and 480C.
