Abstract
According to the invention, a processing aid is used to improve processing in a green (uncured) rubber composition, such as in downstream in-plant processing of an innertube compound, and maintaining, or more preferably, reducing the air permeability of the cured composition, e.g., innertube compound. In embodiments, another of the advantages of the present invention is that the processing aid according to the invention can be used in addition to or as a replacement for the other processing aids and oils.
