ポリ(ビニルエチルエーテル) 化學(xué)特性,用途語,生産方法
化學(xué)的特性
Poly(ethyl vinyl ether) is a opaque amber viscous liquid, It is a hydrophobic material that is insoluble in water or other polar solvents.
使用
Poly(ethyl vinyl ether) can used as a plasticiser for cellulose nitrate and cellulose resin lacquers, as a base for pressure-sensitive adhesives in films and tapes, especially in surgical applications. Also used for non-irritating surgical casts requiring moisture permeability and to impart dry-film flexibility and increased viscosity of photochemical resist-coating compositions.
製造方法
To a flask containing 200 gm of benzene is added 1.0 gm of aluminum chloride. The mixture is stirred vigorously to suspend the catalyst and then the gradual addition of 200 gm (2.78 moles) of vinyl ether is begun. The reaction is exothermic, and when the temperature rises to 60°-80°C the addition is slowed so that only 1-2 gm of vinyl ethyl ether is added at one time. Polymerization is detected by the onset of turbidity and a slight brown color. When the brown color disappears, the next increment of vinyl ethyl ether is added. After the complete addition the reaction mixture is heated to 80°C. The benzene and volatiles are steam-distilled off, and the residue amounts to about 144 gm (72%) of a yellow balsamlike product.
Preparation of Poly(vinyl ethyl ether) Using Aluminum Chloride Catalyst
危険性
Moderately toxic.
安全性プロファイル
Moderately toxic by intraperitoneal route. When heated to decomposition it emits acrid smoke and irritating vapors.
