UV-induced cationic polymerization of divinyl ether-onium salts system by laser photolysis

Abstract In a study of the mechanism of UV-induced cationic polymerization of divinylether-onium salt systems, UV laser photolysis was performed. The transient absorption of cationic species was recorded in the range of 330–420 nm at room temperature. The decay rate constant of cationic species was found to be 0.1 μs −1 .
