Sažetak
Copolymers of methacryl-N, N0-diisopropylurea (MA-DiPrU) 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 (Bz2O2) at 708C for 48 hr. Copolymers regardless of the ratio of comonomers in the feed decompose thermally at 200–2508C under the separation of isopropylisocyanate (iPrNCO). Residues after the removal of iPrNCO are thermally stable nanoporous crosslinked copolymers of methacryl-isopropylamide (MA-iPrA) with EDMA which decompose by a one-step mechanism between 2808C and 4508C. Nonporous model copolymers poly(MA-iPrA-co-EDMA) of similar composition, prepared by copolymerization of MA-iPrA with EDMA, also decomposed by a one-step mechanism as shown by TGA measurements.
