    Abstract: Medical dressings are disclosed that include multiple exposed pressure sensitive adhesives. One of the pressure sensitive adhesives includes a bioactive agent and is substantially contact transparent. In some embodiments, all of the adhesives are substantially contact transparent. Also provided are methods of manufacturing the medical dressings. By providing multiple exposed pressure sensitive adhesives, the pressure sensitive adhesive formulations can be varied to provide desired properties in different areas of the dressing. A pressure sensitive adhesive that exhibits relatively high tack to skin may be provided around the periphery of the dressing while a pressure sensitive adhesive incorporating a bioactive agent is provided in the center of the dressing. Alternatively, a higher tack pressure sensitive adhesive may be provided at two opposing sides of the dressing with a bioactive adhesive located in between the opposing portions of higher tack adhesive. The present invention also provides methods of transferring adhesives using a mask such that the adhesive is transferred to selected areas of a receiving surface. The mask may be provided in the form of a liner including a plurality of voids formed therein.

    Abstract translation: 公开了包括多个暴露的压敏粘合剂的医用敷料。 压敏粘合剂之一包括生物活性剂并且基本上是接触透明的。 在一些实施方案中，所有粘合剂基本上是接触透明的。 还提供了制造医用敷料的方法。 通过提供多个暴露的压敏粘合剂，可以改变压敏粘合剂制剂以在敷料的不同区域中提供所需的性质。 可以在敷料的周围设置在皮肤周围具有相对较高粘性的压敏粘合剂，同时在敷料的中心设置包含生物活性剂的压敏粘合剂。 或者，可以在敷料的两个相对侧设置较高的粘性压敏粘合剂，其中具有位于较高粘性粘合剂的相对部分之间的生物活性粘合剂。 本发明还提供了使用掩模转移粘合剂使得粘合剂被转移到接收表面的选定区域的方法。 掩模可以以包括形成在其中的多个空隙的衬垫的形式提供。

    Abstract: An improved 2,6-dialkylaniline process carried out by reacting an aromatic amine having an unsubstituted ortho position with an olefin in the presence of an aluminum anilide type catalyst followed by catalyst deactivation and distillation to remove 2,6-dialkylaniline. The distillation residue is catalytically hydrogenated and then distilled to recover additional 2,6-dialkylaniline.
