Abstract
PURPOSE: A combination of a specific sulfonic acid, an amine and a phosphine is used as a catalyst to produce polyethylene terephthalate polyester of less diethylene glycol content with high transparency and good color tone.
CONSTITUTION: After esterification of (A) the acid component mainly consisting of terephthalic acid with (B) the glycol component mainly consisting of ethylene glycol, (C) a sulfonic acid of formula I [Ar is aromatic; X is halogen; Y is -NO2, -NO, -N=NR; R is H, lower alkyl, aryl; Z is H, N(R)4; j is 0W4; k, l are 1W3] or its acid anhydride such as p-toluenesulfonic acid, (D) an amine such as methylamine and/or (E) a phosphine such as methylphosphine are combined so that the molar content of N and/or P becomes 0.2W4 times the molar content of the sulfonic group to effect the polycondensation reaction.
