Rubber composition comprised of cis-1,4-polyisoprene and polymeric di-maleamic acid 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 polymeric di-maleamic acid and to articles of manufacture having at least one component comprised thereof, including tires. The polymeric di-maleamic acid has been observed to enhance green strength of such rubber composition.
