Patent number: 8821901Abstract: 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.Type: GrantFiled: April 5, 2010Date of Patent: September 2, 2014Assignees: A.V.
