Abstract

High mol. wt. aromatic polyester is made workable by heating the polyester in the presence of a surface active cpd. Specif., a nonionic surfactant is used. Wt. ratio of surfactant to polyester is between 0.01 and 0.5. The polyester is heated to 90-250 degrees C. Method is used for recovering waste aromatic polyesters for further processing. The waste polyester is rapidly converted into a pdt. which can be used as a component in synthetic waxes, or a raw material for unsatd. polyesters, alkyd resins, polyesteramides and polyurethanes.
