The shearing, Peeling strength and thermo and photo-resistance of polyester-polyeether blockcopolymer were improved by adding cresol-formaldehyde epoxide resin. The conditions of blending were searched and a mechanism of blending has been ProPosed basedon IR, DTA, TM and TG measurements. It is shown that the reaction cf ePoxide group with the end group (-OH, -COOH) of polyester-polyether takes place during the melting of the blends.
