Vinyl polymers are a group of polymers derived from vinylmonomers such as styrene (polystyrene), vinyl chloride (polyvinylchloride), ethylene (polyethylene), propylene (polypropylene) and butadiene (polybutadiene). A polymer is a generic term used to describe a substantially long molecule. ... A vinyl is an organic molecule containing a vinyl group: H R / C = C / H H where R represents a functional group such as a hydrocarbon or halogen. ... In chemistry, a monomer (from Greek mono one and meros part) is a small molecule that may become chemically bonded to other monomers to form a polymer. ... Styrene (also vinyl benzene, ethenylbenzene, phenethylene, cinnamene, diarex HF 77, styrolene, styrol, styropol) is an organic compound which is an aromatic hydrocarbon having the chemical formula C8H8. ... Styrofoam redirects here. ... Vinyl chloride, also known as chloroethene in IUPAC nomenclature, is an important industrial chemical chiefly used to produce its polymer, polyvinyl chloride (PVC). ... Vinyl siding Polyvinyl chloride (PVC) is a widely-used plastic. ... Ethylene or ethene is the simplest alkene hydrocarbon, consisting of two carbon atoms and four hydrogens. ... Polyethylene or polyethene is an engineering thermoplastic heavily used in consumer products. ... Propylene, also known by its IUPAC name propene, is an organic compound having the chemical formula C3H6. ... Polypropylene lid of a Tic Tacs box, with a living hinge and the resin identification code under its flap Polypropylene (PP) is a thermoplastic polymer, used in a wide variety of applications, including food packaging, textiles, laboratory equipment, and polymer banknotes. ... Butadiene can refer to either one of two hydrocarbon chemical compounds which are alkenes that are isomers of each other. ... Polybutadiene is a synthetic rubber that has a high resistance to wear and is used especially in the manufacture of tires. ...
The vinylpolymer may be a homopolymer of the vinyl compound, or a copolymer of the vinyl compound and a copolymerizable monomer.
That is, the vinylpolymer having the unit (2) (hereinafter sometimes refers as the vinylpolymer (2)) maybe a homo- or copolymer of the vinyl compound (1), or may be a copolymer of the vinyl compound (1) and a copolymerizable monomer.
Such a vinylpolymer (2) is capable of easily forming a uniform and transparent amorphous glass by means of a variety of methods for forming a coating layer (for example, a variety of coating methods such as spin coating, casting).
The vinylpolymer is unusual, however, because it is based only in part on hydrocarbon feedstocks: ethylene obtained by processing, or cracking, natural gas or petroleum.
Vinyl resin, however, is still one step away from being a usable material: it must be combined with selected chemical additives and modifiers to achieve the various properties desired in vinyl end-products.
Vinyl's inherent flame retardance is especially important in electrical applications: vinyl resists ignition and flame spread, burns at a higher temperature than many other materials, and commonly will not burn once the flame source is removed -- characteristics that often make vinyl the material of choice in construction and transportation applications as well.
