ABSTRACT:
A process for preparing block, and/or graft copolymeric compositions by forming an intimate mixture of two or more polymers, at least one of which includes one or more amino junctions and at least one of the remaining polymers includes one or more carboxylic acid junctions and an effective amount of a phosphite compound, and thereafter heating the intimate mixture at a temperature and for a time sufficient to form the desired block, and/or graft copolymers.
