摘要： An adhesive composition which lacks functional groups containing reactive hydrogen moieties and contains no post-polymerization chemical crosslinker finds use in transdermal drug delivery systems. The invention enables the administration of drugs containing a reactive functional group, which drugs have heretofore not been able to be administered by the transdermal route using conventional acrylic adhesives.

摘要： Pressure sensitive adhesive formulations of an acrylic polymer grafted with a hydrogenated rubber. In one embodiment, the polymer contains a hydroxyalkyl (meth)acrylate ester which is crosslinked with a titanium-containing chelated metal alkoxide. The adhesive formulations provide an exceptional combination of adhesion to low energy surfaces and high temperature cohesive strength.

摘要： A graft copolymer for use as an adhesive for drug delivery patches or dressings that is resistant to dissolution in the presence of skin penetration enhancers comprises copolymerized acrylic and, optionally, vinyl monomers, to form a backbone polymer, to which are grafted polymeric moieties that do not absorb greater than 3% by weight of a skin-penetration enhancer under thermodynamic equilibrium at 25.degree. C. if independently introduced into an excess of the enhancer. Preferably, the grafted polymers are selected from the classes of polybutylene, polysaccharide, poly(ethyleneoxide/propyleneoxide), and polyamide polymers, and specific grafted polymers will depend on the specific enhancers used in a particular drug delivery system.
