Tg of polyvinyl acetate
WebPolyvinyl acetate is widely used as a paint or an adhesive because it is highly soluble in solvents like ketone, ester, and alcohol.Polyvinyl acetate is solved with solvent in order to lower its glass transition temperature from its usual 38-40ﾟC down to room temperature or lower, for better flowability andworkability as an adhesive agent. Glass transition … WebVinyl acetate is used mainly for the production of other industrial chemicals, such as polyvinyl acetate, an important polymer for which it is the precursor. These chemicals are used mainly to make glues for the packaging and building industries. They are also used to make paints, textiles, and paper.
