20110123800 | UREA-BASED PRESSURE-SENSITIVE ADHESIVES - Non-silicone urea-based adhesives are disclosed which are prepared by the polymerization of reactive oligomers with the general formula X—B—X, where X is an ethylenically unsaturated group and B is a unit free of silicone and containing urea groups. The reactive oligomers can be prepared from polyamines through chain extension reactions using diaryl carbonates followed by capping reactions. Adhesive articles, including optical adhesive articles may be prepared using the disclosed non-silicone urea-based adhesives. | 05-26-2011 |
20120100326 | URETHANE-BASED PRESSURE SENSITIVE ADHESIVES - Non-silicone, urethane-based adhesives are disclosed which are prepared by the polymerization of reactive oligomers with the general formula X-A-B-A-X, where X is an ethylenically unsaturated group B is a unit free of silicone, and A is a urethane linkage. The adhesives are optically clear, self wetting and removable. Adhesive articles, including optical adhesive articles, may be prepared using the disclosed non-silicone urethane-based adhesives. | 04-26-2012 |
20130122079 | TRANSDERMAL ADHESIVE COMPOSITIONS, DEVICES AND METHODS - A stable transdermal adhesive composition comprising: an adhesive comprising a washed polymerization reaction product of at least two ethylenically unsaturated monomers; and at least one pharmaceutically active compound which is susceptible to oxidative degradation; wherein the at least two ethylenically unsaturated monomers, if present in the adhesive as unreacted monomers, are present at a level of less than 200 ppm of total unreacted monomer, based upon the total weight of the adhesive, methods of making the composition, a transdermal drug delivery device using the composition, methods of making the device, and methods of delivery the pharmaceutically active compound are provided. | 05-16-2013 |
