Summary

The effect of various antioxidants of the type of alkylphenol derivatives, secondary aromatic amines, condensation products of diphenylamine with acetone and hydroquinoline derivatives on the course of synthesis and thermo-oxidative ageing of copolyester-ethers on the basis of dimethyl terephthalate, 1,4-butanodiol and a,w-bis(hydroxy)oligooxytetramethylene has been compared. It has been found that a sufficient efficiency in the stage of synthesis revealed only several phenolic stabilizers and a majority of amino-derivatives. For the amino stabilizers the highest anti-ageing activity has also been found.
