Abstract

Disclosed are an entrained polymer or an entrained polymer composition, and a method for forming and adhering an entrained polymer structure to a substrate using the entrained polymer or an entrained polymer composition. The method includes providing a substrate configured to receive application of a molten entrained polymer. A particulate entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least a base polymer and a particulate active agent. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer.
