    摘要: The present invention relates to biocidal articles. In an embodiment the biocidal article comprises a plurality of polymers having biocidally active groups. The polymers are attached to a surface and may have a polydispersity less than 3. The biocidally active groups may comprise at least one of a quaternary ammonium salt, a quaternary phosphonium salt or a chloroamine. The attached polymers may be any microstructure, topology or composition, such as, a homopolymer, block copolymer, multiblock copolymer, a random copolymer, graft polymer, a branched or a hyperbranched polymer, and a gradient copolymer. The present invention also comprises a process for the preparation of a biocidal article. Embodiments of the process comprise polymerizing radically polymerizable monomers from an initiator attached to a surface, wherein at least a portion of the monomers comprise a group capable of being converted to a biocidally active group, and converting the group to the biocidally active group.

    摘要: A polymer formed by controlled radical polymerization includes groups that can be modified after controlled radical polymerization to form a radical. The polymer can be the reaction product of a controlled radical polymerization of radically polymerizable monomers, wherein at least one of the radically polymerizable monomers includes at least one group that can be modified after the controlled radical polymerization to form a radical. A compound includes a first group that is stimulated upon application of energy to the molecule to tether the molecule to a surface or to another polymer chain and a second group comprising a controlled radical polymerization initiator functionality. A block copolymer includes at least a first segment to impart a predetermined functionality to a target surface and at least a second segment including functional groups to interact with the targeted surface to attach the block copolymer to the surface. The first segment can free of functional groups that interact with the surface to attach the block copolymer to the surface.

    摘要: The invention is directed to a microemulsion polymerization comprising adding a polymerization catalyst precursor, such as a transition metal complex in the higher of two accessible oxidation states, an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion. Radically polymerizable monomers and a reducing agent may then be added to the emulsion. The reducing agent converts the catalyst precursor to a catalyst for polymerization of the first monomer from the initiator. In certain embodiments the organic solvent may comprise radically polymerizable monomers. The aqueous solution may comprise a surfactant. Further embodiments are directed to an ah initio polymerization process comprising adding a polymerization catalyst precursor; an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion, wherein the organic solvent comprises second radically polymerizable monomers, adding a reducing agent to convert the catalyst precursor to a catalyst for polymerization of the first radically polymerizable monomer from the initiator; and adding first radically polymerizable monomers to the emulsion.
