Abstract
PURPOSE: To prepare an isocyanurate ring-containing polyester amide 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 aromatic dicarboxylic acid monoester, with a polyhydric alcohol.
CONSTITUTION: (A) A polyamidecarboxylic 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) a monoalkyl ester of an aromatic dicarboxylic acid, expressed by the formula (R is alkyl), 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.
