Abstract

Supported initiators for the radiation-activated polymerization of cationically-polymerizable compounds, particularly epoxide group-containing compounds, are described. The supported initiators comprise a particulate carrier and a photocatalytic ionic salt. The supported initiators are especially useful for the polymerization of cationically-polymerizable compounds in which the ionic salt alone is not soluble.
