Abstract: A block copolymer is provided that includes a first block having pendant phosphorus-containing groups and a second block having fluorinated groups. Compositions containing the block copolymer as well as articles that include the block copolymer are also provided. The block copolymer can be used to provide a lower surface energy to a surface, particularly a metal-containing surface.

Abstract: A method of making a nonwoven fiber web comprises: providing a melt-blown nonwoven fiber web comprising bonded primary fibers having an average fiber diameter of 2 to 100 microns, wherein the primary fibers comprise a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units; opening at least a portion of the melt-blown nonwoven fiber web to provide loose primary fibers; combining the loose primary fibers with secondary fibers; and forming a secondary nonwoven fiber web comprising the primary fibers and secondary fibers. A fiber web preparable according to the method and a multicomponent fiber including a first phase comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units and a second phase comprising a non-biodegradable polymer.

Abstract: An article. The article includes a polymer foam having a first major surface and a second major surface; and discrete domains of a therapeutic composition at least partially surrounded by the polymer foam; wherein an exterior surface of each discrete domain substantially conforms to a portion of the first major surface of the polymer foam; wherein the article comprises a first major surface and a second major surface; and wherein a portion of the first major surface of the polymer foam and the exterior surfaces of discrete domains form the first major surface of the article.
