Frederick W. Stavely was a researcher at the Firestone Tire & Rubber Company who in 1953, while investigating the reaction of butyl lithium on butadiene discovered that polymerization of isoprene with metallic lithium produced polyisoprene with a high cis content. High cis content is associated with enhanced strain crystallization, important during WWII because other synthetics did not exhibit the crystallization effect.
In 1950, Stavely served as chairman of the American Chemical Society Rubber Division.
In 1972, Stavely received the Charles Goodyear Medal in recognition of this discovery.
