A transdermal drug delivery device involving a macromonomer-containing acrylate or methacrylate copolymer, a softener, and a drug. Also a pressure sensitive skin adhesive involving a macromonomer containing acrylate or methacrylate copolymer and a softener.

Matrix for transdermal drug delivery

Transdermal drug delivery compositions comprising pressure sensitive adhesive microspheres that contain a softening agent and/or a drug. Typically the microspheres contain at least 10 wt-% of a softening agent. The drug and/or softening agent can be incorporated into the microspheres during or after their formation.

Adhesive microsphere drug delivery composition

The invention relates to a resin transfer molding preform binder resin that comprises at least one aromatic polyepoxide, a fluorene epoxide that is different than the aromatic polyepoxide and having a defined structure, and a 9,9-bis(aminophenyl)fluorene curing agent. The binder resin is a solid, room temperature stable, essentially nonsintering powder that displays a glass transition temperature greater than about 40.degree. C. Also disclosed are preforms made with the binder resin and a method for preparing the preforms.
