Ethane, along with ethylbenzene, is fed to a dehydrogenation reactor with a catalyst capable of simultaneously producing styrene and ethylene.
en.wikipedia.org The following are listed in order of decreasing rate of polymerization: polystyrene, polymethyl styrene, polycyclopentadiene, polyacrylate, polyethyl acrylate, polymethyl methacrylate, polyvinyl acetate, polyisoprene, polyisobutene, and polyethylene.
en.wikipedia.org It can be made synthetically by polymerizing a monomer such as styrene that has been emulsified with surfactants.
en.wikipedia.org The resin is usually epoxy, but it may also be vinyl, acrylic, polyester, or oleoresin, and could even be styrene, polyethylene, or polypropylene.
www.wired.com The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery.
