Abstract

PURPOSE: To prepare an isocyanurate ring-containing polyester imide useful for electrical insulation varnish, etc. and having a high softening temperature, by reacting a reaction product of an isocyanurate ring-containing polyisocyanate and an acid anhydride group-containing carboxylic acid, with a polyhydric alcohol, etc.
CONSTITUTION: (A) A polyimidocarboxylic acid prepared by reacting (a) an isocyanurate ring-containing polyisocyanate prepared by trimerization of a diisocyanate, e.g. 4,4'-diphenylmethane diisocyanate, etc., with (b) an acid anhydride group-containing carboxylic acid, e.g. trimellitic anhydride, etc., is reacted with (B) a polyhydric alcohol, e.g. ethylene glycol, etc., and if necessary (C) the other carboxylic acids, e.g. terephthalic acid, etc., to give the desired polymer.
