Abstract
A polyesteramide containing free hydroxyl groups is made by heating together (1) dimethyl terephthalate; (2) a linear diamine (e.g. butylene or hexamethylene diamine); and (3) a polyhydric alcohol having at least three hydroxyl groups (e.g. trimethylol propane, hexane triol, glycerine or pentaerythrite). In addition the reaction mixture may include a dihydric alcohol (e.g. ethylene, 1:3-propylene or 1:4-butylene glycol) or another dicarboxylic acid (e.g. adipic or sebacic acid) which may be added as such, as the dimethyl ester or as a diamine salt. The polyesteramide may be dissolved in cresol and used as a copper wire varnish either as such or after addition of an isocyanate, preferably a blocked triisocyanate. In examples polyesteramides are made from (1) dimethyl terephthalate, hexamethylene diamine and glycerine; (2) dimethyl terephthalate, hexamethylene diamine, trimethylol propane and ethylene glycol; (3) dimethyl terephthalate, adipic acid, hexamethylene diamine, trimethylol propane and 1:4-butylene glycol; (4) dimethyl terephthalate, adipic acid/hexamethylene diamine salt and trimethylol propane; (5) dimethyl terephthalate, adipic acid, 1:4-butylene diamine, trimethylol propane and 1:4-butane diol.
