A vinyl ester resin is prepd. by reacting an unsaturated monovalent basic acid e.g. acrylic acid or methacrylic acid with a compd. of epoxy in the presence of a reactive catalyst compd. of formula (I) and a polymerization inhibitor. In (I), R1 is H or methyl; R2 and R3 are methyl or ethyl. The catalyst compd. is selected from N, N- dimethylamino ethylacrylate, N,N-dimethylamino ethyl methacrylate, N,N-diethylamino ethylacrylate or N,N-diethylamino ethyl methacrylate.
