Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
Some familiar household synthetic polymers include: Nylons in textiles and fabrics, Teflon in non-stick pans, Bakelite for electrical switches, polyvinyl chloride (PVC) in pipes, etc. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate.
Produces various kinds of synthetic resins. The Company's products include polyvinyl chloride pipes and films. The Company also manufactures construction materials and electronic industry materials. It is one of the Mitsubishi core companies. Hishi Plastics USA, an ISO 9001:2008 Quality System certified subsidiary, located in Lincoln Park, New ...
In the early 1970s, the carcinogenicity of vinyl chloride (usually called vinyl chloride monomer or VCM) was linked to cancers in workers in the polyvinyl chloride industry. Specifically workers in polymerization section of a B.F. Goodrich plant near Louisville, Kentucky , were diagnosed with liver angiosarcoma also known as hemangiosarcoma , a ...
Among the earliest examples in the wave of new polymers were polystyrene (first produced by BASF in the 1930s) [4] and polyvinyl chloride (first created in 1872 but commercially produced in the late 1920s). [4] In 1923, Durite Plastics, Inc., was the first manufacturer of phenol-furfural resins. [136]
Phthalates can plasticise ethyl cellulose, polyvinyl acetate phthalate (PVAP) and cellulose acetate phthalate (CAP), all of which are used to make enteric coatings for tablet and capsule medications. These coatings protect drugs from the acidity of the stomach, but allow their release and absorption in the intestines.
The list of synthetic polymers, roughly in order of worldwide demand, includes polyethylene, polypropylene, polystyrene, polyvinyl chloride, synthetic rubber, phenol formaldehyde resin (or Bakelite), neoprene, nylon, polyacrylonitrile, PVB, silicone, and many more. More than 330 million tons of these polymers are made every year (2015).
