An aromatic diamine compound represented by formula (1): ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, are each a hydrogen atom or a lower alkyl group; and an aromatic diamine compound useful as an intermediate for the synthesis of the above compound (1), represented by formula (2): ##STR2## The compound (1) alleviates the problems of the prior art, and is unlikely to cause crystallization by heat and has a melting point and a glass transition temperature both higher than those of conventional compounds.
一种芳香二胺化合物,化学式表示为(1):##STR1##其中R.sub.1和R.sub.2,可能相同也可能不同,均为氢原子或较低的烷基基团;以及一种用作合成上述化合物(1)的中间体的芳香二胺化合物,化学式表示为(2):##STR2##该化合物(1)缓解了先前技术的问题,并且不太可能因热而结晶,其熔点和玻璃化转变温度均高于传统化合物。
