The technology chosen for synthetic rubber production was based on Buna S research because Buna S could be mixed with natural rubber and milled on the same machines, and because the raw materials (the monomers) were available. This rubber was particularly suited for tire treads because it resisted abrasive wear; and it retained sharper impressions in molds, calender rolls, and extruders than
Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2.This derivative of benzene is a colorless oily liquid, although aged samples can appear yellowish.The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.

The first rubber band was developed in 1843, when an Englishman named Thomas Hancock sliced up a rubber bottle made by some New World Indians. Although these first rubber bands were adapted as garters and waistbands, their usefulness was limited because they were unvulcanized. Hancock himself never vulcanized his invention, but he did advance the rubber industry by developing the masticator
