  • Publication number: 20050215727
    Abstract: An adhesive composition is provided that is water-insoluble yet water-absorbent, i.e., capable of absorbing up to 15 wt. % water or more. The composition is composed of a film-forming hydrophilic polymer with at least one linear segment having a plurality of recurring polar groups along the polymer backbone, a complementary multifunctional polymer with a plurality of recurring functional groups that noncovalently bind to the polar groups on the film-forming polymer, and a plasticizer. A method for manufacturing the adhesive composition is provided as well.

  • Publication number: 20050208110
    Abstract: A rapidly dissolving film is provided for delivery of an active agent to a moist body surface, e.g., mucosal tissue. The film comprises a film-forming binder, a rapidly dissolving polymeric material, and an active agent.

  • Publication number: 20050113510
    Abstract: A method of selecting components for use in water-absorbing pressure-sensitive adhesive compositions is provided. The method involves selecting a film-forming polymer, a ladder-like non-covalent crosslinker that is capable of forming a ladder-like interpolymer complex with the film-forming polymer selected, and selecting a carcass-like non-covalent crosslinker that is capable of forming a carcass-like complex with at least one of the film-forming polymer selected or the ladder-like non-covalent crosslinker selected. The adhesive hydrogels provide high adhesion in a swollen state and bridge the gap between conventional pressure sensitive adhesives and bioadhesives. Methods for preparing and using the resulting compositions are also disclosed.

  • Publication number: 20050048103
    Abstract: An adhesive composition is provided that contains both a hydrophobic phase and a hydrophilic phase, wherein the hydrophobic phase is composed of a crosslinked hydrophobic polymer composition and the hydrophilic phase is a water-absorbent blend of a hydrophilic polymer and a complementary oligomer capable of crosslinking the hydrophilic polymer through hydrogen bonding, ionic bonding, and/or covalent bonding. The composition is useful as a bioadhesive, for affixing drug delivery systems, wound dressings, bandages, cushions, or the like to a body surface such as skin or mucosal tissue.
