Abstract

A partially-neutralized, fatty-acid modified alkylbenzene sulfonic acid is useful as a processing aid for use with natural, synthetic or reclaimed rubber, and it is useful in the mastication and peptizing steps of rubber processing, as well as in dispersing and emulsifying additives for the rubber and in improving the wetting characteristics of the rubber. The partially-neutralized, fatty-acid modified sulfonic acid may be formulated into a composition having particular utility as a lubricant for rubber by mixing with a fatty acid amide, a polyethylene glycol, a wax and, optionally, a fluorinated surfactant.
