Aspects regarding environment polarity influence over alcoholisis process of the polyvinyl acetate

Previous research evidenced that the polarity of the reaction mixture has great influence on the alcoholisis process. In the presence of superior alcohols (C-2-C-10) or aromatic hydrocarbons the viscosity of the gel-phase shows important changes. Considering these aspects, in the present paper the influence of paraffin oil on the consistency of the gel-phase was assessed. The results evidenced that small amounts of paraffin oil reduce considerably the reaction-mixture viscosity, thus the alcoholysis process can be carried out in classical reactors equipped with common stirrer.
