摘　　要：为了扩大聚乙烯醇(PVA)的应用领域,通过添加第二单体与醋酸乙烯(VAc)共聚,制备改性PVA,改性后的PVA可以改善某一方面的性能,实现特定领域的应用。主要从羧基改性、乙烯基改性、磺酸基改性三方面介绍了聚乙烯醇共聚改性的方法,为聚乙烯醇的改性应用提供借鉴与参考,也为聚乙烯醇新的应用方向提供思路。In order to expand the application field of polyvinyl alcohol,modified PVA is often prepared by adding a second monomer and copolymerizing with vinyl acetate(VAc).The modified PVA can improve a certain aspect of performance and achieve specific field applications.This article mainly introduces the methods of polyvinyl alcohol copolymerization modifi-cation and the application of modified polyvinyl alcohol from three aspects:carboxyl modification,vinyl modification,and sulfonic acid modification,providing reference and reference for the modification application of polyvinyl alcohol,and also providing ideas for new application directions of polyvinyl alcohol.
