ABSTRACT:
Anaerobically curable sealant and adhesive compositions comprising polymerizable acrylate esters or methacrylate esters and a redox system as accelerator are stabilized by the addition of sulfamide derivatives containing the group ##STR1## The stabilization may be further improved by using the sulfamides in combination with phenolic anti-oxidants, particularly sterically hindered phenols, without reducing the curing rate of the compositions.
