In an initiator system are incorporated: a) a compound of the formula:
where R, = H or a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, an alkenyl group having 2 to 18 carbon atoms, a cycloalkyl or cycloalkenyl group having 5 to 8 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, a furfuryl group or the group
where Y represents a methyl group and Z an alkyl group having 2 to 4 carbon atoms or Y and Z together form a 1,3- or 1,4- alkylene group having 3 or 4 carbon atoms which is substituted or not with an alkoxy group having 1 to 4 carbon atoms; R2 = a substituted or unsubstituted alkyl group or alkenyl group having 4 to 20 carbon atoms, a cycloalkyl group or cycloalkenyl group having 5 to 8 carbon atoms, an alkaryl group having 4 to 16 carbon atoms in the alkyl group or a furfuryl group; R3 and R4 may be the same or different and represent a hydrogen, a chlorine or a bromine atom or a phenyl group, a substituted or unsubstituted alkyl group or alkoxy group having 1 to 4 carbon atoms, or a dialkyl amino group of which the alkyl groups have 1 to 4 carbon atoms and may be substituted with a hydroxyl group, and b) a synergistic amount of Na, K and/or Li-salt of an organic acid that is compatible with the curable compositions: and optionally some amount of solvent c for component b. The initiator system cures rapidly and has good storage stability.
在引发剂体系中加入: a) 式中化合物:
其中 R, = H 或具有 1 至 18 个碳原子的取代或未取代的烷基、具有 2 至 18 个碳原子的烯基、具有 5 至 8 个碳原子的环烷基或环 烯基、具有 6 至 20 个碳原子的取代或未取代的芳基、糠基或以下基团
其中 Y 代表甲基,Z 代表具有 2 至 4 个碳原子的烷基,或 Y 和 Z 共同形成具有 3 或 4 个碳原子的 1,3- 或 1,4- 亚烷基,该亚烷基被具有 1 至 4 个碳原子的烷氧基取代或未被烷氧基取代;R2 = 具有 4 至 20 个碳原子的取代或未取代的烷基或烯基、具有 5 至 8 个碳原子的环烷基或环 烯基、烷基中具有 4 至 16 个碳原子的芳烷基或糠烷基;R3 和 R4 可以相同或不同,代表氢、氯或溴原子或苯基、取代或未取代的烷基或具有 1 至 4 个碳原子的烷氧基,或其中烷基具有 1 至 4 个碳原子并可被羟基取代的二烷基氨基,以及 b) 与可固化组合物相容的有机酸的 Na、K 和/或 Li 盐的协同量:以及用于成分 b 的一定量的溶剂 c。该引发剂体系固化速度快,储存稳定性好。
