Abstract
Inhibition by oxygen of the peroxide-initiated cure of a composition based on (meth)acrylates or other compounds containing free radical-polymerizable functional groups is mitigated by inclusion of one or more polythiols in the composition. Such compositions may be formulated as multi-part systems, which are useful for the preparation of coatings and sealants.
