A curable composition including a monomer having at least one curable acrylic functionality, an accelerator and optionally a free radical initiator, wherein the accelerator is a compound of the formula <IMAGE> wherein R' is H or alkyl; when R' is H, R is substituted or unsubstituted cyclohexyl, alkenylamino, or C3-C10 branched alkyl; and when R' is alkyl, R is aralkyl. Such compositions are useful as fixturing (e.g., threadlocking) compositions, and overcome the problems of poor solubility in organic non-polar media and temperature constraints associated with the use of saccharin per se as an accelerator in such compositions. Also disclosed is a corresponding method of polymerizing compositions containing acrylic-functional compounds, and a method of making the substituted saccharin compounds from the corresponding substituted benzene sulfonamide. Alkenylamido-substituted saccharin compounds and alkyl, aralkyl-disubstituted saccharin compounds are specifically disclosed.
