Abstract
A copolyester polyether is produced by reacting an oligomer mixture derived from terephthalic acid, a glycol and a hydroxyaromatic carboxylic acid successively with terephthalic acid and a glycol-ester or glycolether of a hydroxyaromatic carboxylic acid or a mixture thereof and polymerizing the product. All reactions are conducted at at least 220 DEG C. Glycols specified are linear alkylene glycols of 2-10 carbon atoms, e.g. ethylene glycol. Free glycol or hydroxy-acid may be added with the glycol-ester or glycol-ether. Hydroxy aromatic carboxylic acids specified are p-hydroxybenzoic acid and its chloro and methyl derivatives and vanillic acid. The oligomer mixture may comprise a mixture of p-b -hydroxyethoxybenzoic acid b -hydroxyethyl ester and an oligomer of 3 ethylene glycol units condensed with 2 terephthalic acid units. The process may be a batch or continuous process. In continuous operation the oligomer mixture is allowed to flow down column 1. The terephthalic acid is introduced from conveyor 4 and the glycol or glycol ester of ether via valve 5. A polycondensation catalyst, e.g. antimony or manganese acetates, sulphonic acids or compounds of amphoteric elements, e.g. B, Be, Al, Zn, Pb, Sn, Fe, Ti, As or Co may be added with the terephthalic acid and a stabilizer, e.g. triphenyl phosphate or other metal alkyl, or aryl phosphate or phosphite or a phosphorus acid may be added with the glycol or glycol ester or ether. An inert gas enters at 6. The eliminated water escapes via fractionating column 2. From the bottom of the column part of the material is returned to the top by pump 8a and the remainder is removed to reactor 10 for polycondensation at 220-260 DEG C./< 0.1 mm. Hg. It is sprayed on to revolving drum 14 and when sufficiently polymerized is removed by scraper 16 and conveyers 17 and 18. The eliminated water escapes via a vacuum pump attached to tube 15. 11 is a heating jacket.
