ABSTRACT:
A process for forming random copolymers which comprises forming a polymer melt containing one or more polyamides and one or more acidic or basic inorganic materials, such as ammonium bisulfate, ammonium biphosphate and sodium biphosphate; and heating said melt for a period of time sufficient to form the desired amount of the copolymer. The random copolymers may be fabricated into films or other products which have desirable properties, and can be useful in making injection molded or extruded products of improved properties.
