Zusammenfassung:A method for reducing chatter in an extrusion process, which includes the steps of preparing an extrusion composition by combining a polymer composition with a chatter-reducing formulation, and extruding the extrusion composition to provide a substantially continuous extrudate. The chatter-reducing formulation comprises an alkyltin mercaptide and dibutyltin dilaurate. The resultant extrudate exhibits reduced chatter, which is categorized according to the Reed Scale as less than or equal to 2.
