Abstract

PURPOSE: To convert primary amino groups into secondary amino groups ant obtain a modified aromatic diamine composition for producing plastics by reacting an aromatic diamine having the primary amino group with an unsaturated compound such as acrylic acid esters.
CONSTITUTION: An aromatic diamine such as tolylenediamine is reacted with an unsaturated compound expressed by the formula CH2=CH-Y (Y is electron attractive group) to convert amino group in the aromatic diamine into secondary amino group according to the Michael addition reaction in which the primary amine is reacted with the unsaturated compound (e.g. n-butyl acrylate or 2- ethylhexyl acrylate). Thereby, the objective new modified aromatic diamine for producing plastics is obtained. A neutral or an acidic catalyst such as p- toluenesulfonic acid or acetic acid is preferably used in the Michael addition reaction.
