聚乙烯醇（PVA）是一种无色、无毒、无腐蚀性、可生物降解的水溶性有机聚合物。目前，PVA 除作为维尼纶的原料外，还广泛应用于纺织品上浆、涂料、粘合剂、乳化剂、薄膜等工业领域。然而

PVA 聚合物粉末特别适合用作建筑砂浆添加剂。它可与羟丙基甲基纤维素 HPMC 保水剂一起使用，以改善水泥。砂浆的柔韧性、保水性，提高砂浆的粘结性。此外，还能提高摩擦

在聚合物（由多单元大分子组成的化合物）中，PVA 是独一无二的，因为它不是由称为单体的单单元前体分子聚合而成的。相比之下，聚乙烯醇是通过将另一种聚合物聚醋酸乙烯酯（PVAc）溶解在以下物质中制成的

纺织用尺寸和纤维聚乙烯醇粘合剂，具有非常好的粘合性和成膜性，价廉物美，主要用于纯涤纶或涤棉纱的打浆，有时也用于与丙烯酸一起打浆高支数的纯尺寸涤纶纱。

建筑胶粘剂和粘合剂 以聚乙烯醇为原料的建筑胶粘剂包括腻子胶粘剂、涂料粘合基材等，其规模占总量的 40% 以上。目前应用最广泛的是 PVA 17-99、PVA 20-99、

(1) Compared with cellulose ether, guar ether is more soluble in water. The performance of the pH guar ether was essentially unaffected. (2) Under the condition of low viscosity and low dosage, guar gum can replace cellulose ether in the

1. Polyvinyl alcohol is soluble in water and generally needs to be heated to 65～75℃ in order to dissolve completely. Slightly soluble in dimethyl sulfoxide. It is soluble in glycerol at 120～150℃, but becomes jelly when cooled to room temperature.
