Photopolymerization of acrylamide with benzophenone/methylated-β-cyclodextrin inclusion complex in the presence of jeffamine based dendrimers as coinitiators in aqueous media

摘要

BP/Me-P-CD inclusion complex was synthesized and used in photoinduced free radical polymerization of acrylamide as a type II photoinitiator in the presence of a dendritic co-initiator. Characterization and photophysical studies of the inclusion complex were determined by ~1H NMR, UV, laser flash photolysis and phosphorescence spectroscopy. According to acrylamide polymerization of the BP/Me-β-CD water soluble photoinitiator, BP/Me-β-CD initiates polymerization of acrylamide effectively with six and twelve armed dendritic co-initiators in aqueous media. The 24 armed dendritic co-initiator was not as efficient as the six and twelve armed dendritic co-initiators with the BP/Me-β-CD inclusion complex, due to the sterical hindrance of the amine groups in the co-initiator.
