Abstract
PURPOSE:To obtain the titled polymer having high strength and giving an optically anisotropic molded article by melt-molding, by polymerizing 3-chloro-4- oxybenzoic acid, 4-oxybenzoic acid, 4,6-diphenyldicarboxylic acid, hydroquinone, etc., at specific ratios. CONSTITUTION:3-Chloro-4-acetoxybenzoic acid, 4-acetoxybenzoic acid, 4,4'- diphenyldicarboxylic acid and hydroquinone acetate, etc., are subjected to deacetylation polycondensation at 250-350 deg.C and to polycondensation at 370 deg.C under reduced pressure to obtain the objective polymer composed of the structural units of formulas I-III [X is (substituted)phenylene, etc.] and formula IV (Y is phenylene or group of formula V). The sum of the units of formula I and formula II is 90-1mol.% and sum of the formula III and formula IV is 10-99mol.% based on the whole polymer. The molar ratios of I/II and III/IV are 10/0-0.1/9.9 and 10/0-3/7, respectively and the logarithmic viscosity of the polymer is 0.35-20.0dl/g measured in pentafluorophenol at 60 deg.C and a concentration of 0.1g/dl.
