Abstract: Films that comprise an active agent for delivery to a tissue. The films may include carboxyls that form a chemical association with the active agent and/or hydrophilic domains or particles that comprise the active agent.

Abstract: A tissue contacting material comprising a plurality of regions comprising an outer region serving as a protective barrier, one or more inner regions, and a tissue contacting region. The plurality of regions each comprise one or more of a plurality of polymers selected from the group consisting of a first polymer comprising a crosslinked hydrophilic polymer and a second crosslinked polymeric matrix, formed of a crosslinkable polymer adapted to incorporate the first polymer without substantially reacting or crosslinking with the first polymer. The first and/or second polymers provide the respective regions with one or more properties including swellability in the presence of water, active agent content, permeability to the diffusion of active agent from or through the layer, moisture vapor permeability, and adhesion to tissue.

Abstract: Reaction injection molding is utilized as a method for making an abrasive article that includes supplying an effective amount of abrasive particles to at least a portion of an abrasive article mold and supplying a binder precursor matrix that includes at least two interactive components to the abrasive article mold. When the binder precursor matrix is cured, the abrasive particles are secured within a binder formed from the binder precursor matrix. An abrasive article includes a plurality of bristles including an increased amount of abrasive particles, wherein a ratio of binder to abrasive particles is at least about 1:3 by weight.

Abstract: The present invention relates to a unitary brush (such as a cup brush, for example) which has abrasive particles secured to at least some of its bristles via a first coating. The unitary brush is made by providing a unitary brush, coating at least a portion of the surfaces of the bristles with a first coating, adhering abrasive particles to at least some of the coated bristles and curing the first coating.

Abstract: Self-healing articles resistant to oxidizing agents and useful for surface conditioning of sheets, especially metal sheets, are described. The articles comprise a plurality of compacted, stacked non-woven web elements, the web elements each comprising entangled fibers bonded together at points of mutual contact by a bonding agent. The article is resistant to an oxidizing agent or agents, has a Shore A hardness in the range of 70 to 93 and a void volume in the range of 2 to 30 percent. The non-woven articles can be configured into any of a variety of convenient and useful shapes, such as roll shapes, slab or bar shapes. The methods of making these articles are also described.
