Rubber composition comprised of cis-1,4-polyisoprene and 4,4'-(para or meta-phenylenedilsopropylidine) dianiline and articles, including tires, having at least one component comprised thereof

摘要

This invention relates to rubber compositions comprised of cis-1,4-polyisoprene and a 4,4'-(para or meta-phenylenediisopropylidine) dianiline and to articles of manufacture having at least one component comprised thereof, including tires. The 4,4'-(phenylenediisopropylidine) dianiline acid has been observed to enhance green strength of such rubber composition.
