摘要： A normally nontacky but potentially tacky adhesive lift-off tape which comprises an adhesive film composition which normally exhibits a plastic nontacky state but is convertible to an elastomeric tacky state by the application of substantial stress, i.e., stretching sufficiently or striking with typewriter type, as well as the process of applying the said adhesive film. This film composition consists essentially of thermoplastic and elastomeric A-B block copolymers wherein the A-blocks are thermoplastic and the B-blocks are elastomeric and about 20-120 parts per one hundred parts by weight of the block copolymers of certain normally solid resins adapted to associate principally with the thermoplastic A-blocks of said copolymers. In these copolymers the A-blocks are derived from styrene or styrene homologues and the B-blocks are derived from conjugated dienes or lower alkenes. The normally solid resins preferably are selected from the group consisting of alpha-methylstyrene-vinyl toluene copolymers and coumarone-indene copolymers.

摘要： This invention relates to a novel pressure sensitive adhesive formed of a liquid and solid rubber which is substantially resin free. Preferably the adhesive is formed of a weight ratio of solid rubber to liquid rubber of about 1:0.5 to about 1:7. When a thermoplastic rubber is used, an endblock associating resin can also be used with the block copolymer solid rubber composition for improving adhesion and hold properties of the composition. A minor amount of tackifier can be added without affecting the improved properties of the present invention. The adhesive can preferably be cross linked with a sulfur, sulfur-bearing agents, peroxide, isocyanate or an aluminum isopropylate composition. These adhesives exhibit improved adhesion in cold weather and oily surface applications and other properties. The pressure sensitive adhesives can be used in health care, industrial and drug delivery systems. The adhesives can be processed by a hot melt process for providing improved ecological benefits.
摘要翻译：本发明涉及一种由基本上无树脂的液体和固体橡胶形成的新型压敏粘合剂。优选地，粘合剂由固体橡胶与液体橡胶的重量比形成为约1:0.5至约1:7。当使用热塑性橡胶时，端嵌段缔合树脂也可以与嵌段共聚物固体橡胶组合物一起使用，以提高组合物的粘合性和保持性。可以添加少量的增粘剂而不影响本发明的改进的性能。粘合剂优选与硫，含硫剂，过氧化物，异氰酸酯或异丙醇铝组合物交联。这些粘合剂在寒冷天气和油性表面应用和其它性能方面表现出改进的粘合性。压敏粘合剂可用于保健，工业和药物输送系统。粘合剂可以通过热熔融方法加工，以提供改善的生态效益。

摘要： Body member conformable disposable articles and processes for their preparation are described. A preferred embodiment is a disposable absorbent article comprising a flexible, elastic, moisture impermeable backing film, an absorbent layer superposed thereon and a moisture permeable topsheet joined to the backing film along the edges of the topsheet. A portion of at least one longitudinal edge of the backing film has been folded upon itself and heat sealed together at the fold so that when the backing film is laid flat the aforementioned longitudinal edge will be in stretched condition, thus conferring body member conformability to the article.
