The patent describes how novel polymers containing nitrile and thioamide groups are prepared by contacting a polymer of acrylonitrile or vinylidene cyanide with hydrogen sulfide at a temperature below about 50C in the presence of a catalytic amount of an alkali metal carbonate. The polymers are useful as coatings and in the preparation of fibers and films.
