In an industrial setting, vinyl acetate is often mixed with a solvent and subjected to high temperatures and pressures in a reactor. The reaction involves the formation of free radicals that initiate the polymerization process, leading to the growth of polymer chains. Through this method, polyvinyl acetate is synthesized, which may vary in molecular weight depending on the reaction conditions. The control over the polymer molecular weight is crucial, as it significantly impacts the properties of the final polyvinyl alcohol product.
