    • Abstract The present invention relates to a process of making polymerized hydrogels, in particular hydrogel adhesives which e.g. are capable of attaching to mammalian skin and can be used in various personal care products, such as waste-management articles, cosmetic and medical devices and a variety of functional articles to be worn by a human. The process described herein is characterized by influencing the adhesiveness by varying the oxygen content of the atmosphere present during the polymerization. Utilizing this method it is possible to influence one performance parameter (adhesiveness) independently from the others (e.g. rheology behaviour). This opens ways to a more easy and more flexible production of such hydrogels. In addition it is possible to obtain hydrogels with a combination of rheology and adhesiveness properties that were not or not so easily obtainable by conventional means. Lowering the oxygen content of the atmosphere at the polymerization zone also gives an additional benefit in lowering the amount of residual monomer(s).
    • 摘要本发明涉及一种制备聚合水凝胶的方法,特别是水凝胶粘合剂, 能够附着于哺乳动物皮肤,并可用于各种个人护理产品,例如废物处理用品,化妆品和医疗装置以及人类所穿的各种功能性物品。 本文所述的方法的特征在于通过改变聚合期间存在的气氛的氧含量来影响粘附性。 利用该方法,可以独立于其它方式影响一个性能参数(粘合性)(例如流变行为)。 这开创了一种更容易和更灵活地生产这种水凝胶的方法。 此外,可以获得具有通过常规方法不容易获得的流变性和粘合性的组合的水凝胶。 在聚合区域降低气氛的氧含量也可以降低残留单体的量带来额外的益处。
