摘要： A polymeric composition is disclosed which has sealant and preferably also adhesive properties and which is suitable for use as a protective dressing for application to the skin. The composition comprises a chemically cross-linked hydrophilic polymer and a support matrix such as a high molecular weight hydrophobic polymer. The hydrophilic polymer is a water-swellable polymer which absorbs or adsorbs water but which is water-insoluble. The composition preferably includes a tackifyer which may be provided by a low molecular weight fraction of a hydrophobic matrix or by a distinct adhesive component such as a gum or a low molecular weight polymer. The composition is particularly suitable for use as a sealing ring in conjunction with a post-surgical drainage appliance wherein the hydrophilic polymer is incorporated in a form such as to provide a transmission system for liquid.
摘要翻译：公开了一种聚合物组合物，其具有密封剂并且优选地也具有粘合性质，并且适合用作施用于皮肤的防护敷料。组合物包含化学交联的亲水性聚合物和载体基质如高分子量疏水性聚合物。亲水性聚合物是吸水或吸附水但水不溶性的水溶胀性聚合物。组合物优选包括可由低分子量级分的疏水性基质或不同的粘合剂组分例如胶或低分子量聚合物提供的增粘剂。该组合物特别适合用作与手术后排液器具结合的密封环，其中亲水性聚合物以形式提供以提供用于液体的传播系统。
