摘要： A water soluble film useful in unit-dose chemical packaging is disclosed. The film may include: a water soluble saccharide and a polyvinyl alcohol copolymer consisting essentially of: (a) from 80 to 99 mole percent of vinyl alcohol and vinyl ester monomer; and (b) from 1 to 20 mole percent of a pyrrolidone comonomer. Such compositions may be used to provide a water-soluble film simultaneously satisfying requirements in regard to water solubility, biodegradability, and physical properties, even when used for packaging a broad range of harsh, oxidizing chemicals.

摘要： A water soluble polyvinyl alcohol copolymer having a diad syndiotacticity of greater than about 60% and less than about 70%. In some embodiments, the water soluble polyvinyl alcohol copolymer is soluble in water at a concentration of at least 1 wt% at a temperature of less than 100°C. In other embodiments, the composition is soluble in water at a concentration of at least 5 wt% at a temperature in the range from about 90°C to less than 100°C. The high solubility of the high syndiotactic poly vinyl alcohols disclosed herein may provide various advantages as described herein, including ease of processing and decreased use of harmful solvents.

摘要： Water soluble films and coatings herein address the problem of water insolubility, color formation, and brittleness upon exposure to oxidizing chemicals, including strong or aggressive oxidizing chemicals. The water soluble films or coatings may include a water soluble polymer and a reactive precursor, such as an alkanolamine or an alkyl alkanolamine. The reactive precursor is water soluble and reactive with oxidizing compounds. Water soluble films or coatings herein may also include a water soluble polymer and an additive mixture including an alkanolamine or an alkyl alkanolamine. The films or coatings, upon exposure to an oxidizing chemical for 8 weeks at 40°C and ambient humidity, may dissolve fully or achieve 90% dissolution at times of less than 10 minutes. The water soluble films and coatings may advantageously be used with oxidizing chemicals while maintaining water solubility, acceptable color, and flexibility, such as in unit dose packaging, even over extended exposure periods.
摘要翻译： 这里的水溶性薄膜和涂层解决了暴露于氧化性化学物质（包括强烈或侵蚀性的氧化性化学物质）时的水不溶性，着色形成和脆性的问题。 水溶性薄膜或涂层可包括水溶性聚合物和反应性前体，如链烷醇胺或烷基链烷醇胺。 反应性前体是水溶性的，与氧化性化合物反应。 本文中的水溶性薄膜或涂层还可包括水溶性聚合物和包含链烷醇胺或烷基链烷醇胺的添加剂混合物。 在40℃和环境湿度下暴露于氧化剂8周后，薄膜或涂层可以在少于10分钟的时间内完全溶解或达到90％溶解。 水溶性薄膜和涂层可有利地与氧化化学品一起使用，同时保持水溶性，可接受的颜色和柔韧性，例如在单位剂量包装中，即使在延长的暴露期间。
