    摘要: A water soluble dermal treatment film for dressing burns, surface wounds, cuts, scrapes, rashes or other dermal wound or lesion comprises a flexible sheet-like dressing made of polyalkyloxazoline. The dressing can have a structural layer and a pressure sensitive adhesive layer. The structural layer can be made of a polyalkyloxazoline composition formulated to obtain a flexible structural sheet. The pressure sensitive adhesive layer can be formulated to obtain pressure sensitive properties, maintaining the treatment film in position during its use. At such time the treatment film is to be removed, it can be removed without harsh scrubbing methods with a warm aqueous spray or soak. The sheet-like treatment means can be reinforced or impregnated with medicinal compositions to induce healing, reduce infection or stabilize the skin surface.

    摘要: Hot melt adhesives which include at least 5% of a thermoplastic elastomer block copolymer having a Vicat softening temperature of at least 60.degree. C. and a melting point of at least 100.degree. C., have improved thermal resistance properties and can be applied with conventional hot melt application equipment at temperatures of between about 149.degree. C. and about 204.degree. C. The adhesives are particularly suited to use in above-the-belt locations in automobile interiors and in furniture bonding. Especially suitable thermoplastic elastomers are polyether-polyester and polyether-polyamide segmented polymers with melting points above 149.degree. C. Hot melt adhesives based on these thermoplastic elastomers can be formulated to provide a range of properties including pressure sensitive properties and contact adhesive properties.

    摘要: The present invention is a hot melt adhesive composition comprising at least one ingredient present in an encapsulated form. The encapsulated ingredient may be any known hot melt adhesive formulation ingredient as well as any hot melt adhesive additive such as antioxidants and fragrances for which there is a desirable change in adhesive properties by isolating such ingredient for a duration of time. The encapsulated ingredient is released from the shell by means of pressure, temperature, diffusion, pH, light, radiation, ultrasound, and combinations thereof. Hot melt adhesive compositions comprising at least one encapsulated ingredient are useful for a variety of novel products including self-supported friction glue sticks, non-tacky pelletized pressure sensitive adhesives, cohesive adhesive systems, hot melt adhesive compositions exhibiting improved thermal stability and odor, as well as for a variety of other adhesive applications.

    摘要: A polymeric composition in pellet form comprising a tacky hot melt composition, comprising a) from about 5% by weight to about 90% by weight of a thermoplastic polymer, b) from about 0% by weight to about 65% by weight of a tackifying resin, c) from about 0% to about 50% by weight of a plasticizer, d) up to about 2% by weight of an antioxidant, and a pelletizing aid, wherein the tacky hot melt composition has some minimum amount of tackifier or plasticizer and is a pressure sensitive adhesive having a storage modulus, G', at about 25.degree. C., of less than about 5.times.10.sup.6 dynes/cm.sup.2, and each pellet has a substantially tack-free surface.This invention further discloses a polymeric composition in pellet form suitable for molding articles. The composition comprises a tacky hot melt composition comprising at least one high molecular weight triblock copolymer of the general configuration A-B-A and a plasticizer and a pelletizing aid. The pelletizing aid substantially surrounds the tacky composition such that the molded articles are substantially free from surface tack.A method of forming the pellets is also disclosed.
