1. A method for processing a polymer comprising:
- providing a polymer;
adding an effective amount of a foam cell nucleating agent to the polymer to reduce degradation of the polymer, carbon formation or gel formation during processing of the polymer;
mixing the polymer and the foam cell nucleating agent and processing the mixture to obtain an unfoamed product, whereby degradation in the unfoamed product, gel formation or carbon formation is reduced.

Abstract
A method for reducing degradation during processing of polymers. An effective amount of a foam cell nucleating agent to reduce degradation in a polymer is added to the polymer. The polymer and the foam cell nucleating agent are mixed to obtain a molten plastic and processed to obtain an unfoamed product, resulting in a reduction of degradation in the unfoamed product. The processing is preferably selected from extrusion and injection molding.
