PROCESS FOR PREPARING COMPOUND OF UNSATURATED DICARBOXYLIC ACID IMIDES AND RESIN OF THE SAME IMIDES

摘要

A process for preparing a compound of unsaturated dicarboxylic acid imides allows the compound of a following formula obtained through a dehydrating cyclization of an unsaturated dicarboxylic amic acid compound in the presence of catalysts and thereafter a vacuum distillation of the ring-closed compound: whereby the compound of unstaturated dicarboxylic acid imides can be obtained at high yield and purity without requiring complicated treating steps.
