Název v původním jazyce

Photopolymerization of monomers with two different reactive groups

Popis výsledku v původním jazyce

UV photopolymerization of three bifunctional monomers bearing epoxy and vinyl groups was studied. Monomers used were glycidyl methacrylate (GMA), glycidyl vinyl ether (GVE) and 3,4-epoxy-1-butene (butadiene monoxide, BMO). The homopolymerization experiments were carried out at room temperature using 2-isopropylthioxanthone (ITX) and/or (4-methylphenyl)[4-(2-methylpropyl) phenyl] iodonium hexafluorophosphate (IC250) as photoinitiators. Fourier transform infrared (FTIR) spectroscopy was used to follow thefunctional groups conversion during polymerizations. The transmission, the attenuated total reflectance (ATR) and the specular reflection techniques were applied. During the free radical (ITX) initiated photopolymerization the double bond shows higher reactivity within GMA than BMO, whereas the GVE conversion was negligible. Using the transmission technique, in the presence of IC250 the epoxy group conversion rate is much higher within GVE or BMO as compared with GMA. With GMA photopoly
