POLY(VINYL ACETATE) Chemical Properties,Uses,Production
Chemical Properties
transparent pellets or white powder
History
Polyvinyl acetate was discovered in Germany in 1912 by Fritz Klatte.
The monomer, vinyl acetate, was first produced on an industrial scale by addition of acetic acid to acetylene with a mercury(I) salt[3] but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene.
Uses
drug delivery, hemodynamics, wound dressing, coatings
Production Methods
Polyvinyl acetate is derived from the polymerization of vinyl acetate; the catalysts used in polymerization may include hydrogen peroxide, peroxy sulfates, or various redox combinations. The polymerization process is described as being carried out by charging all ingredients to the reactor, heating to reflux, and stirring until the reaction is complete. Typically, only a part of the monomer and catalyst is initially charged; the remainder is added during the course of the reaction.
Preparation
PVAc is a vinyl polymer. Polyvinyl acetate is prepared by polymerization of vinyl acetate monomer (free radical vinyl polymerization of the monomer vinyl acetate).
Definition
ChEBI: A polymer composed of repeating acetoxyethylene units.
General Description
Poly(vinyl acetate) [PVAc] is a biocompatible and biodegradable polymer as it has hydrolyzable groups in the side chain,also it is non-toxic and non-carcinogenic.Owing to its biologically friendly nature , it is used in various biomedical application such as artificial organ implant, contact lens,cardiovascular devices and cartilage skin. It is also used in wound dressing and various drug-delivery applications. It has been accepted as reference standard for universal calibration in gel permeation chromatography.
Hazard
Questionable carcinogen.
Industrial uses
Polyvinyl acetate is a leathery, colorless thermoplasticmaterial that softens at relatively lowtemperatures and that is relatively stable to lightand oxygen. The polymers are clear and noncrystalline.The chief applications of polyvinylacetate are as adhesives and binders for waterbasedor emulsion paints.
Vinyl acetate is conveniently prepared bythe reaction of acetylene with acetic acid.
Safety Profile
Very low toxicity by ingestion. Questionable carcinogen. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS
Purification Methods
Precipitate it from acetone by addition of n-hexane.
