Abstract Cationically polymerisable compounds, in particular epoxy compounds, can be polymerised by heating in the presence of a catalyst and a co-catalyst. The catalyst employed is a quaternary ammonium salt of an aromatic-heterocyclic com- pound which contains 1 or 2 N-atoms, and a complex halide anion, e.g. PF6?. The co-catalyst employed is a diaryl ethane derivative, preferably benzpinacol, a silyl oligomer thereof, an organic per compound or a quinone.
