Nitrogen-containing heterocyclic (poly)peroxycarboxylic acids having the formula: <IMG> (I) wherein: R and R1 represent, independently of each other, a hydrogen atom or a straight or branched alkyl, (hetero)cycloalkyl, (hetero)aryl, alkylaryl or arylalkyl group, optionally substituted, a carboxylic group, or any other substituent which is non-reactive in the presence of the active oxygen of the peroxycarboxylic group; n is an integer selected from 0, 1 and 2; m is an integer selected from 1, 2 and 3; and x represents an acidic anion selected from HSO4- and CH3SO3and wherein the heterocyclic ring may be condensed with at least one further (hetero)aromatic or (hetero)cycloalkylic ring. The acids have utility inter alia as a polymerization starter or as an oxidizing agent for olefin epoxidation or hydroxylation.
