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 innerliner compound, and maintaining, or more preferably, reducing the air permeability of the cured composition, e.g., innerliner compound. In embodiments, another of the advantages of the present invention is that the processing aid according to the invention can be used in very low levels relative to the other processing aids and oils.
