    摘要: A process for preparing a vinyl alcohol copolymer, which comprises adding at least one specific olefin derivative containing phenyl group to a solution of vinyl ester copolymer when the predetermined polymerization conversion has been attained, removing an unpolymerized monomer and hydrolyzing the copolymer. The hydrolyzed copolymer easily gives transparent film which has not fish eyes or surface roughness without generation of fumes or bad odors and coloration during molding.
