Abstract: The invention provides a pressure-sensitive adhesive composition for medical applications comprising a blend of at least two components comprised of about 5 to about 95% by weight of a first component comprised of at least one acrylic pressure-sensitive adhesive and about 5 to about 95% by weight of a second component comprised of either (a) at least one elastomer with a tackifying resin, or (b) at least one thermoplastic elastomer, wherein the resulting pressure-sensitive adhesive demonstrates a T.sub.0 of at least 1 N/dm and a T.sub.48 of less than 12 N/dm when adhered to skin. The pressure-sensitive adhesive composition is prepared either in the presence of a solvent or is alternatively prepared by melt blending. A method of preparing such an adhesive is also disclosed.

Abstract: Composite films and film laminates comprising at least one elastomeric core and a surrounding nonelastomeric matrix preferably prepared by coextrusion. The film when stretched and allowed to recover will create an elastomeric composite.

Abstract: An adhesive tape is provided which comprises a woven cloth, a polymer embedded into the cloth so as to cause the warp and weft fibers of the cloth to bond together at their overlapping points but not to completely encase the fibers, and a pressure sensitive adhesive coated onto at least a portion of the polymer, wherein the adhesive tape is hand tearable in the down-web and in the cross-web direction. A method of manufacturing such a tape is also provided.

Abstract: Microtextured elastomeric laminates comprising at least one elastomeric layer and at least one thin skin layer is preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers and then allowing the laminate to recover.

Abstract: A unified, composite tape structure is provided. The tape comprises two outer pressure-sensitive adhesive layers joined via melt processing. A method of making the tape comprising the use of melt processing is also disclosed. In the method a plurality of layers are melt processed and simultaneously joined to form the unified composite.

Abstract: An embossable sheet, having at least one stress-whitening layer comprising a blend of:a) at least one heat-stable polymer selected from the group consisting of polypropylene and a polymethyl alkene, said alkene having from about 3 to about 7 carbon atoms,b) at least one other polymeric material immiscible therewith, andc) an effective amount of an antioxidant, said sheet exhibiting stress-whitening which is stable at 136.degree. C. for at least about 7 days.

Abstract: Polymer blends of non-crystalline mesomorphous polypropylene and a polymer compatible with such polypropylene and the method of making such polymer blends are provided. Such compatible polymer blends exhibit substantial maintenance of structural integrity after exposure to gamma irradiation and provide heat sealing properties, puncture resistance, and tear strength. Films, fibers, and other articles made from such blends may be used in various applications, including medical articles such as medical packaging films, ostomy pouches, and transdermal delivery patches, which may require sterilized storage prior to usage.

Abstract: Irradiated polypropylene articles of non-crystalline mesomorphous polypropylene and a method for preparing the articles are provided. The articles are irradiated with a sterilizing dosage of ionizing radiation. The irradiated articles such as films and blown microfiber webs are substantially undegraded after storage periods of as long as six months.
