Abstract:
A method of using an accelerator to increase the rate, or reduce the temperature, of cure of an energy-polymerizable composition comprising the step of forming a composition by combining an accelerator, a cationically curable material and at least one salt of an organometallic complex cation, wherein said cation contains at least one carbon atom bonded to a transition metal atom, and wherein said accelerator is a compound selected from the group consisting of classes 1, 2, 3,whereinclass 1 compounds are represented by Formula III: wherein each R1, independently, is hydrogen, chloro, iodo, bromo, fluoro, hydroxy, cyano, nitro, nitroso, carboxyl, formyl, acetyl, benzoyl, trialkylsilyl, trialkoxysilyl, a substituted or unsubstituted alkyl, alkenyl, alkynyl, and alkoxy groups containing up to 30 carbon atoms, one to four substituted or unsubstituted aromatic rings wherein two to four rings are fused or unfused, or two R1s taken together form at least one ring which is saturated or unsaturated and the ring is substituted or unsubstituted;class 2 compounds are represented by Formula IV: wherein each R2 is the same or different as the other R2s and is the same materials as those described for R1 in the Class 1 accelerators; or two R2s are replaced with a double bonded oxygen to form a carbonyl group; andclass 3 compounds are represented by Formula V: wherein each R1, independently, has the same definition as in Formula III and R3 is selected from C1 to C10 substituted or unsubstituted alkyl groups, or groups of one to four substituted or unsubstituted aromatic rings wherein two to four rings are fused or unfused.
