Synthesis and Characterization of Trifunctional Methacryloyloxy Monomers

doi:10.7517/j.issn.1674-0475.2008.05.403

Abstract

Abstract: Two trifunctional monomers based on diethanolamine (or triethanolamine) and methacryloyl chloride were synthesized and characterized by ¹H-NMR,real-time infrared spectroscopy(RT-IR) and dynamic mechanical thermal analysis(DMA).The results showed that both rate of polymerization and final conversion increased with increase of photoinitiator concentration,and decreased with increase of light intensity.2-Hydroxy-2-methyl-1-phenyl propan-1-one(1173) was a more effective photoinitiator to these monomers than that of benzophenone(BP).As the addition of the two monomers to Tetraethylene Glycol Dimethacrylate(SR209),the mechanical properties of the curing products were different.

Key words: monomers, photopolymerization, kinetics, RT-IR, DMA
