Foams for biomedical applications were made from polyvinyl alcohol, polyvinyl alcohol / polyvinyl pyrrolidone blend and their nanocomposites with nanoclay by clean processes. Air was entrapped into the aqueous polymer solutions during vigorous mixing and then the solutions were freeze-dried. The foams structure was stabilized by crosslinking via gamma

Syndiotactic polyvinyl formate and derived polyvinyl alcohol
Journal of Polymer Science Part A: General Papers, 1963AbstractA study was made of the effect of polymerization temperature on the syndiotacticity of polyvinyl formate. Vinyl formate was polymerized with ultraviolet light initiation in the temperature range from −20 to +30°C. The value of (Ep — Et)/2 obtained, 4.5 kcal./mole, is characteristic of those values obtained by other workers for the free radical ...

Polyvinyl Alcohol and Polyvinyl Acetate
2020Basically only ethylene and air are needed for the production of polyvinyl acetate (PVAc) and its polymer analogous products, such as polyvinyl alcohol and polyvinyl butyrate. Polyvinyl acetate serves as the precursor for polyvinyl alcohol and, directly or indirectly, the polyvinyl acetals.
