Abstract Cationically polymerisable compounds, for example cyclic ethers, can be thermally polymerised if an aromatic iodonium salt of the formula I Image (I) in which Ar1, Ar2, M, X and n are as defined in claim 1, is used as the catalyst and an agent which forms free radicals on heating and has the formula III or IV Image (III) Image in which R2, R3, R5, R6, R8 and m are as defined in claim 1, for example a benzpinacol silyl ether, is used as the co-catalyst. The process is of particular importance for heating-curing epoxide resins as a one-component system. .
