Abstract
Cationically polymerizable compounds can be polymerized photochemically and thermally when a combination of (a) an aromatic iodonium salt, (b) a photoinitiator from the series comprising the aromatic carbonyl compounds and (c) an agent which forms free radicals on heating is used as the catalyst. Polymerization is preferably effected in two stages, first photochemically and then thermally, or vice versa. Preferred substrates are epoxide compounds.
