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 core/shell copolymers having a rubbery, preferably crosslinked core mainly of units derived from butadiene, and an outer shell mainly of a copolymer of styrene and acrylonitrile. Such copolymers do not require the presence of functional groups capable of reaction with the hydroxyl groups of the poly(vinyl alcohol).
