Photopolymerization of hybrid monomer 3-(1-propenyl)oxypropyl acrylate

Hybrid monomer 3-(1-propenyl)oxypropyl acrylate, combining easy free radical and fast cationically polymerizable group, was synthesized by phase-transfer catalyzed substitution, isomerization and subsequently esterification. Its photopolymerization kinetics was monitored by Fourier transform real-time infrared spectroscopy (FTIR) with a horizontal sample holder. The results indicated that hybrid monomer showed inter-group interaction in photopolymerization process, which decreased moisture sensitivity to cationic photopolymerization process, and represented higher efficiency of photopolymerization when compared with blend system.
