Recent Progress in the Stabilization of Polypropylene Fibers

Abstract

Preliminary data on the efliciency of two new light stahilizers, belonging to the hindered amine group, show that these products are very suitable for the stabilization of polypropylene fibers and stretched tapes. The new additives are very resistant to the leaching action of hot water, even if surfactants are added. They also exhibit good long-term antioxidant properties.
