ABSTRACT:
There is disclosed a method of forming pure white polymers of 2-pyrrolidone when using SO.sub.2 as the activator. The method involves the use of the rubidium or cesium salt of 2-pyrrolidone as the alkaline catalyst in place of the sodium or potassium salt customarily used and which cause the formation of yellow polymer.
