Abstract

PURPOSE: To prepare a polyester amide useful as varnish for enameled wire, by the ester-exchange of an aromatic diamide dicarboxylic acid diester and tris(2-hydroxyethyl)isocyanurate, followed by the reaction of the product with a polyol and a polycarboxylic acid.
CONSTITUTION: An aromatic diamide dicarboxylic acid diester II (R1 is alkyl; R2 is arylene) is prepared by reacting an aromatic dicarboxylic acid monoalkyl ester I which may contain other dicarboxylic acid monoalkul ester with an aromatic diisocyanate such as 4, 4'-diphenylmethane diisocyanate. The molar ratio of the monoalkyl ester to the diisocyanate is pref. 1.9W2.0 to 1. The diester II thus obtained is made to react with tris(2-hydroxyethyl)isocyanurate pref. in a molar ratio of 1:1.3-2.0. The reaction product is, if necessary, further reacted with a polyhydric alcohol such as ethylene glycol and a polybasic acid such as dimethyl terephthalate to obtain the objective polyester amide.
