Abstract: PURPOSE:To obtain polyester useful for fiber having excellent brightness, transparency and yarn-making workability, by a method wherein terephthalic acid is esterified with ethylene glycol and then calcium cpd., cobalt cpd. and phosphorus cpd. are added to the reaction mixt. CONSTITUTION:A dicarboxylic acid consisting mainly of terephthalic acid contg. 4-carboxybenzaldehyde of 100-1000ppm is esterified with a glycol consisting mainly of ethylene glycol until a conversion of no less than 95% to an ester is obtained. Then calcium cpd., cobalt cpd, and phosphorus cpd. in an amount determined by formulae I-IV are added to the reaction mixt. The resulting mixt. is immediately subjected to polycondensation. The most preferred method of the above esterification reaction is that in which a slurry composed of the dicarboxylic acid and the glycol is supplied to yarn, in which 50-150wt% of BHT based on the amount of said dicarboxylic acid consisting mainly of terephthalic acid is present, in order to carry out the esterification in view of diethylene glycol content in the polymer.

Abstract: NEW MATERIAL:1,2-Bis(2-chlorophenoxy)ethane-4,4'-dicarboxylic acid chloride of formula I . USE:A raw material of high-rigidity polymer. It has high melting point and flame retardance. It has higher reactivity than the compound having ester group or carboxyl group at the terminal group, and can be polymerized under mild polymerization condition. PREPARATION:The compound of formula I can be prepared by reacting 1,2-bis (phenoxy)ethane-4,4'-dicarboxylic acid chloride of formula II with Cl in the presence of a solvent selected from 1-8C chlorinated hydrocarbons and 1-2C chlorinated carbons. The solvent is e.g. chlorobenzene, cholorotoluene, chloroxylene, etc., and the Cl is usually chlorine gas. The preferable molar ratio of Cl/ starting substance is 2-4, especially 2-3.5. The yield can be improved by adding 0.1-2wt%, based on the starting substance, of a Lewis acid, especially iodine to the reaction system.
