  2. Polyvinyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Polyvinyl_alcohol

    Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest application in China is its use as a protective colloid to make PVAc dispersions. In Japan its major use is the production of Vinylon fiber. [7] This fiber is also manufactured in North Korea for self-sufficiency reasons, because no oil is required to produce it ...

  3. Vinylon - Wikipedia

    en.wikipedia.org/wiki/Vinylon

    North Korean men wearing uniforms made from vinylon. Vinylon, also known as Vinalon (more common in Korean sources), is a synthetic fiber produced from reaction between polyvinyl alcohol (PVA) fiber and formaldehyde. Chemically it is polyvinyl formal (PVF). Vinylon was first developed in Japan in 1939 by Ichiro Sakurada, Ri Sung-gi, and H ...

  4. Vinyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Vinyl_alcohol

    Vinyl alcohol, also called ethenol (IUPAC name; not ethanol) or ethylenol, is the simplest enol. With the formula C H 2 CH O H , it is a labile compound that converts to acetaldehyde immediately upon isolation near room temperature. [ 1 ]

  5. Vinyl polymer - Wikipedia

    en.wikipedia.org/wiki/Vinyl_polymer

    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")

  6. Polyol - Wikipedia

    en.wikipedia.org/wiki/Polyol

    For instance, polyvinyl alcohol is (CH 2 CHOH) n with n hydroxyl groups where n can be in the thousands. Cellulose is a polymer with many hydroxyl groups, but it is not referred to as a polyol. Polyols from recycled or renewable sources

  7. List of glues - Wikipedia

    en.wikipedia.org/wiki/List_of_glues

    Polyvinyl acetate (PVA) Includes white glue (e.g. Elmer's Glue) and yellow carpenter's glue (Aliphatic resin) (Brands include Titebond and Lepage) Polyvinyl alcohol; Polyvinyl chloride (PVC) Polyvinyl chloride emulsion (PVCE) – a water-miscible emulsion that polymerizes as it cures; Polyvinylpyrrolidone (component of glue sticks) Silicone resins

  8. Ethylene vinyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Ethylene_vinyl_alcohol

    Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol. Because the latter monomer mainly exists as its tautomer acetaldehyde , the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis.

  9. Formvar - Wikipedia

    en.wikipedia.org/wiki/Formvar

    Formvar refers to any of several thermoplastic resins that are polyvinyl formals, which are polymers formed from polyvinyl alcohol and formaldehyde as copolymers with polyvinyl acetate. They are typically used as coatings, adhesives, and molding materials. [1]
