Two low-viscosity monomers, 2-(acryloyloxy)ethyl piperidine-1-carboxylate (AEPC II) and 2-(acryloyloxy)ethyl morpholone-4-carboxylate (AEMC), were synthesized with a non-isocyanate route. The photopolymerization kinetics was monitored by real-time infrared spectroscopy with a horizontal sample holder. The results indicated that AEPC II and AEMC had high ultraviolet curing rates and final double-bond conversions, which could reach 90 and 95%, respectively. The glass-transition temperatures of AEPC II/urethane acrylate resin (1/4 w/w), AEMC/urethane acrylate resin (1/4 w/w), and isobornyl acrylate/urethane acrylate resin (1/4 w/w) mixtures were 37.5, 45.6, and 57 degrees C, respectively. The crosslink density of the AEMC/urethane acrylate resin (1/4 w/w) mixture was lower than that of the isobornyl acrylate/urethane acrylate resin (1/4 w/w) mixture. (C) 2010 Wiley Periodicals, Inc.
