Abstract
PURPOSE: To produce effieicntly titled polyester having good color, by polycondensing an acid component consisting of terephthalic acid and 4,4'-dicarboxybenzanilide with a 2W4C alkylene glycol in the presence of a specified catalyst.
CONSTITUTION: An acid component consisting of terephthalic acid and 1W40mol%, based on the total acids, 4,4'-dicarboxybenzanilide of formula I, wherein R1 and R2 are each H, a lower alkyl or phenyl, is esterified or transesterified with a diol component consisting mainly of a 2W4C alkylene glycol, in the presence of an esterifying catalyst in an inert atmosphere. Then, the reaction mixture is polycondensed at 240W280°C in the presence of a polycondensation catalyst comprising a Ti compound and/or a Ge compound and a trivalent and/or pentavalent P compound and a substituted phenolic compound of formula II, wherein R1 and R2 are each a 1W18C alkyl, R is an n-valent group and can contain a phosphono, an amido or the like and (m) is 1W4.
