Photopolymerization without Light. Polymerization of Acrylates Using Oxalate Esters and Hydrogen Peroxide†
journal contribution
posted on 2006-08-22, 00:00 authored by Andrey A. Ermoshkin, Douglas C. Neckers, Andrei V. FedorovWe define the photopolymerization of acrylates without light as a process wherein the radical
chain polymerization produced by photoinitiators are produced by nonphotochemical means. We use the chemical
reactions of the chemiluminescent lightstick to accomplish this. An important potential application is in producing
“photopolymers” in areas that are not light accessible as in the inside of a tube or behind a pipe. Polymerizable
acrylate mixtures containing dissolved oxalate esters undergo radical chain polymerization when exposed to a
flow of nitrogen gas saturated with hydrogen peroxide vapors. We propose aryloxyoxalyl hydroperoxides to be
the reactive species.
