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 ##STR1## wherein R' is H or alkyl; when R' is H, R is substituted or unsubstituted cyclohexyl, alkenylamino, or C.sub.3 -C.sub.10 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.
一种可固化组合物,包括至少具有一个可固化
丙烯酸官能团的单体,加速剂和可选的自由基
引发剂,其中加速剂是以下式子的化合物:##STR1##其中R'为H或烷基;当R'为H时,R为取代或未取代的环己基,烯基
氨基或C.sub.3-C.sub.10支链烷基;当R'为烷基时,R为芳基烷基。这样的组合物可用作固定(例如,螺纹锁定)组合物,并克服了在有机非极性介质中溶解度差和使用
