yclic azoamidine compounds expressed by the following general formula and salt thereof are disclosed.
wherein R denotes a methyl group or an ethyl group, and R1,R2,R3 and R4 independently denote a lower alkyl group having one to four carbon atoms or a hydrogen atom, provided that a case where R',R2,R3 and R4 are all hydrogen atoms is excluded. The cyclic azoamidine compounds and their salts are useful as polymerization initiators in the production of polymer compounds.
本发明公开了由以下通式表示的环偶氮脒化合物及其盐。
其中 R 表示甲基或乙基,R1、R2、R3 和 R4 独立地表示具有一至四个碳原子的低级烷基或氢原子,但不包括 R'、R2、R3 和 R4 全为氢原子的情况。环状偶氮脒化合物及其盐类可用作生产聚合物化合物的聚合引发剂。
