Rubber composition prepared with cis-1,4-polyisoprene and phthalimide disulfide and articles, including tires, having at least one component comprised thereof

摘要

This invention relates to rubber compositions prepared with cis-1,4-polyisoprene, particularly natural rubber, and phthalimide disulfide and to articles of manufacture having at least one component comprised thereof, including tires. The phthalimide disulfide has been observed to enhance stiffness of natural rubber based rubber compositions.
