Abstract

The present invention relates to the use of sulfur- or phosphorus-containing polymers as processing aids in polyvinyl chloride polymer compositions.

Description

Background technique [0001] The present disclosure relates to the use of polymers as processing aids in polyvinyl chloride polymer compositions. [0002] The present invention relates to polyvinyl chloride and polyvinyl chloride processing. More specifically, but not exclusively, the present invention relates to the use of polymers as processing aids in polyvinyl chloride polymer compositions. The present invention also relates to methods of processing polyvinyl chloride polymer compositions, compositions for synthesizing polyvinyl chloride polymers, processing aids, methods of making polyvinyl chloride compositions and polyvinyl chloride polymer compositions. [0003] Polyvinyl chloride (commonly referred to as PVC) is well known to those skilled in the art. This polyvinyl chloride is a versatile and relatively inexpensive polymer to which many additives can be added in order to obtain the desired processing properties of the polymer as well as one-time processing. Melt pr...
