Abstract
A process for manufacturing polymers containing a degradant component that increases the rate of polymer degradation. The process involves adding a degradant component to a fluid polymer immediately after the polymer is synthesized and while the polymer is still fluid to form a blend of the fluid polymer component and degradant component and mixing the blend of the fluid polymer component and degradant component to distribute the degradant component substantially homogeneously throughout the fluid polymer component.
