My. Goikhman et al., A NEW BIFUNCTIONAL MONOMER, TEREPHTHALOYLBIS(3-METHOXY-4-OXYBENZOYL) DICHLORIDE, AND POLYAMIDES PREPARED FROM IT, Russian journal of applied chemistry, 70(11), 1997, pp. 1793-1797
Terephthaloylbis(3-methoxy-4-oxybenzoic acid was prepared from vanilli
c acid and terephthaloyl chloride. The acid was converted to dichlorid
e, which was used to prepare polyamides by reaction with various aroma
tic diamines. The physicomechanical properties, heat resistance, and t
he structure of the resulting polyamides tin the form of films and fib
ers) were studied.
