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")
The polymer appeared as a white solid inside a flask of vinyl chloride that had been left on a shelf sheltered from sunlight for four weeks. In the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical company Griesheim-Elektron both attempted to use PVC in commercial products, but difficulties in ...
Vinyl chloride is an organochloride with the formula H 2 C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic.
In homebuilt airplanes, the Glasair and Glastar kit planes made extensive use of vinylester fiberglass-reinforced structures. It is a common resin in the marine industry due to its corrosion resistance and ability to withstand water absorption. Vinyl ester resin is extensively used to manufacture FRP tanks and vessels as per BS4994. For ...
An industrially important example is vinyl chloride, precursor to PVC, [3] a plastic commonly known as vinyl. Chessboard made from polyvinyl chloride. Vinyl is one of the alkenyl functional groups. On a carbon skeleton, sp 2-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups.
The monomer, vinyl acetate, was first produced on an industrial scale by the addition of acetic acid to acetylene with a mercury(I) salt, [4] but it is now primarily made by palladium-catalyzed oxidative addition of acetic acid to ethylene.
The transparent polymers are used for the production of lacquers and as adhesives. [1] The hydrolytic cleavage of the ester bonds of vinyl acetate is of industrial significance. [ 2 ]
EVA is made by mixing ethylene and vinyl acetate in a processor, which creates an unrefined mass of EVA. It is fed through rollers that flatten it into sheets, which are then put into a pressure oven. [2] Ethylene-vinyl acetate is based on products from the production of petroleum and natural gas.
