Abstract
Polymers containing a high percentage of vinyl alcohol units are difficult to process into sheet, film, injection-molded objects, or fibers. Such melt-processing is greatly enhanced by admixing certain hydrogenated block copolymers formed by sequential anionic polymerization of butadiene and styrene, followed by hydrogenation, then followed by grafting of maleic anhydride.
