This invention relates to a class of tertiary-alkyltoluenediamines having alkyl groups ortho to an amine group. More particularly the aromatic diamines are represented by the formulas:
wherein R1, R2 and R3 are C1-3 alkyl groups or R2 and R3 are combined to form a C5-6 membered ring.
The above described alkylated aromatic diamines have been found to be well suited for use as a chain extender in forming polyurethane/urea elastomer systems and the mono tert-butyltoluenediamine isomers have been found to be non- mutagenic in the Ames test.
本发明涉及一类叔烷基甲
苯二胺,其烷基正交于一个胺基。 更具体地说,芳香族二胺由以下公式表示:其中 R1、R2 和 R3 为 C1-3 烷基,或 R2 和 R3 组合形成一个 C5-6 分子环。 上述烷基化芳香族二胺已被发现非常适合用作聚
氨酯/
尿素弹性体系统的扩链剂,并且单叔丁基甲
苯二胺异构体在艾姆斯试验中被发现无诱变性。
