Vinyon

Copolymerisation of vinyl acetate and vinyl chloride yields resins of desirable properties they are strong and adhesive, thermoplastic, and are suitable for the manufacture of synthetic fibre (Vinyon).

Before World War II, German developed a synthetic fibre from polyvinyl chloride. In America, a copolymer of vinyl chloride and vinyl acetate was marketed as Vinyon . Dow chemical marketed as Saran a copolymer from vinylidene chloride and vinyl chloride. Saran fibre is characterised by its remarkable resistance of most of chemical reagents and fire.

Acrylan, Dyne/ and Vinyon N are also acrylate resins or acrylics since they are copolymers of acrylonitrile. Acrylic rubbers, including acrylonitrile rubber are also of this general class Refs for Ethyl Methacrylate l)Beil 2, 423, (191) [399] 2)K.Auwers ... 

Fiber or Fibre is any tough substance composed of threadlike tissue, especially when capable of being spun or woven. Fibers may be divided into animal (wool or silk), vegetable (cotton, hemp, flax, ramie, esparto, jute, sisal etc), mineral (asbestos, glass fiber) and artificial (Rayon, Nylon, Orion, Vinyon, Saran etc)... 

When polymerization occurs in a mixture of monomers there will be competition between the different kinds of monomers to add to the growing chain and produce a copolymer. Such a polymer will be expected to have physical properties quite different from those of a mixture of the separate homopolymers. Many copolymers, such as GRS, ethene-propene, Viton rubbers, and Vinyon plastics are of considerable commercial importance. 

In another line of research, scientists began to look for synthetic materials from which artificial blood vessels could he manufactured. Some of the earliest materials to be tried were synthetic fibers, such as nylon, vinyon (a polymer consisting primarily of vinyl chloride), and ivalon (a polymer of vinyl alcohol). These materials were largely unsuccessful because they tended to lose their strength too quickly after implantation. 

The percentages show the share of each fiber in the specified end use each year. b Includes acrylic, anidex, modacrylic, nylon, olefin, polyester, saran, Spandex, TFE-fluorocarbon and vinyon. 

Yarn and monofilament only staple plus tow included under other. c Does not include fiber produced for cigarette filtration purposes. d Includes saran and Spandex yarn also, olefin and vinyon staple and tow. 

The first successful one consisted of 90 percent vinyl chloride copolymerized with 10 percent vinyl acetate. It was dry-spun from acetone and given the trade name Vinyon by its producer, Union Carbide Corporation. (In 1960, vinyon was accepted as a generic name for fibers containing not less than 85 percent vinyl chloride.) It has never been produced in large volume it is used for heat-sealable compositions. 

The modacrylic fibers, like vinyon and unlike the acrylic fibers, have not become general purpose fibers. They can be dyed... 

Filtration is facilitated by use of a Pyrex glass or Vinyon tiller fabric a 30-cm. funnel is advisable. 

Vinyon fabric serves equally well. If a filter cloth is not available, a layer of glass wool is prepared on the funnel the mixed wool and solid are then added to the cracked ice.
