Abstract
New di- or trifunctional vinyl ether monomers were successfully synthesized by the regioselective addition reaction of glycidyl vinyl ether 1 with di- or triacyl chlorides using tetrabutylammonium bromide (TBAB) as a catalyst. Polycondensations of the vinyl ether monomers having chloromethyl groups with terephthalic acid were carried out using 1,8-diazabicyclo[5.4.0]-7-undecene (DBU) to afford polyester oligomers carrying pendant vinyl ether moieties. The vinyl groups of the monomers and the oligomers reacted rapidly, when cationic polymerization was conducted in bulk using photoinitiators upon UV irradiation.
