Abstract Anaerobically-curing compositions are described comprising a first part and a second part with at least a major constituent a polymerizable monomer having at least one .alpha., .beta.-unsaturated carboxyl functionality per molecule of monomer, and with said first part comprising as a first initiator component a parfluoroalkyl sulfonanilide and said second part comprising as a second initiator component a secondary or tertiary aromatic amine. These compositions exhibit a rapid rate of cure in the absence of oxygen. Being two-part compositions, these compositions exhibit extended shelf-life and do not suffer from the problem associated with the gradual decomposition of peroxide or hydroperoxide initiators.
