Many simple hydrocarbons, such as ethylene and propylene, can be transformed into polymers by adding one monomer after another to the growing chain. Rubber is the polymer cis-1,4-polyisoprene with a molecular weight of 100,000 to 1,000,000 daltons.Typically, a small percentage (up to 5% of dry mass) of other materials, such as proteins, fatty acids, resins, and inorganic materials (salts) are found in natural rubber.Polyisoprene can also be created synthetically, producing what is sometimes referred to as "synthetic natural Example: Plexiglas, styrofoam, nylon, etc. The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina.Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Benjamin Goodrich, the company name was changed to the "B.F.
