A general name for polymers or copolymers made from olefin hydrocarbons. Common polyolefins are polyethylene and polypropylene. Isobutylene was the first olefin to be polymerized in 1873, but it was not made into a commercial product until I.G.Farbenindustrie of Germany developed it as a rubber substitute in the 1930s. Ethylene was first polymerized by ICI in England in the 1930s and it became an important plastic during W.W.II for fibers. Large scale applications for polyolefins were developed in the 1960s,when olefins were recognized as inexpensive raw materials. Currently, polyeolfins, polyethylenes, and polypropylenes, etc, are the most common produced polymers.
