<p>Disclosed is a process for producing copolyesters having repeat units from a dicarboxylic acid component comprising at least 90 mol % terephthalic acid and a glycol component comprising about 10-95 mol %, 1,4-cyclohexanedimethanol and from about 90-5 mol % ethylene glycol comprising reacting the dicarboxylic acid component and the glycol component at temperatures sufficient to effect esterification or transesterification and polycondensing the reaction product in the presence of a catalyst and inhibitor system consisting of Mn, Zn, Ti, Ge and P, all parts by weight based on the weight of the copolyester.</p> |
