聚乙烯醇
按聚合度可分为超高聚合度（分子量25～30万）、高聚合度（分子量17～22万），中聚合度（分子量12～15万）和低聚合度（分子量2.5～3.5万）。醇解度一般有完全醇解（醇解度98～100％）、部分醇解（醇解度87～89％）和醇解度78％三种。产品牌号中一般将聚合度的千、百位数字放在前面，醇解度放在后面，例如聚乙烯醇17-99即表示聚合度为1700，醇解度为99％。
PVA具有独特的强力粘接性、皮膜柔韧性、平滑性、耐油性、耐溶剂性、保护胶体性、气体阻绝性、耐磨性以及经特殊处理具有的耐水性，因此除了作纤维原料外，还被大量用于生产涂料、粘合剂、纸品加工剂、乳化剂、分散剂、薄膜等产品，应用范围遍及纺织、食品、医药、建筑、木材加工、造纸、印刷、农业、钢铁、高分子化工等行业。
