ABSTRACT:
A process for enhancing the compatibility of polyester and polyamide in blends by adding thereto an effective amount of an aryl phosphoryl azide compound as for example diphenyl phosphoryl azide, and thereafter heating the composition until the desired enhancement in compatibility is obtained as evidenced by a lower of the individual melting points of the polyester and polyamide in the blend.
