Bisamidrazone compound and vulcanizing agent for fluorine-containing elastomer comprising the same
摘要：
Novel compound, 2,2-bis(4-carboxyphenyl)hexafluoropropane bisamidrazone, obtained by conversion of the carboxy groups of 2,2-bis(4-carboxyphenyl)hexafluoropropane to acid chloride groups, followed by reaction with ammonia; dehydration reaction of the resulting 2,2-bis(4-carboxyphenyl)hexafluoropropane diamide; reaction of the thus obtained 2,2-bis(4-cyanophenyl)hexafluoropropane with alcohol; and reaction of the resulting 2,2-bis(4-carboxyphenyl)hexafluoropropane bisiminoalkyl ether with hydrazine is a useful vulcanizing agent for fluorine-containing elastomer having cyano group.
摘要（中）：

通过将2,2-双（4-羧基苯基）六氟丙烷的羧基转化为酰氯基团，然后与氨反应获得的新型化合物2,2-双（4-羧基苯基）六氟丙烷双胺腙; 得到的2,2-双（4-羧基苯基）六氟丙烷二酰胺的脱水反应; 由此获得的2,2-双（4-氰基苯基）六氟丙烷与醇的反应; 并且所得的2,2-双（4-羧基苯基）六氟丙烷双亚氨基烷基醚与肼的反应是用于具有氰基的含氟弹性体的有用的硫化剂。
