    • 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.

    • The present invention provides dispersible carbon particles and a process for the preparation of dispersible carbon particles. In certain embodiments, the process of the present invention comprises polymerizing monomers from a carbon particle, wherein the carbon particle comprises one or more attached groups comprising one or more transferable atoms or groups. At least a portion of the monomers comprise at least one reactive or ionizable functional group capable of conversion into ionic functional groups. Ionic functional groups enhance the dispersity of the carbon particle in the desired medium, such as the dispersity of carbon black particles in water or aqueous solutions. The process of the present invention may further include converting at least a portion of the reactive or ionizable functional groups into ionic functional groups. The ionic groups may be quaternary ammonium groups, carboxylic acid groups, phosphonium groups, sulfonium groups, iodonium groups or salts thereof.

    • A new polymerization process (atom transfer radical polymerization, or ATRP) based on a redox reaction between a transition metal (e.g., Cu(I)/Cu(II), provides “living” or controlled radical polymerization of styrene, (meth)acrylates, and other radically polymerizable monomers. Using various simple organic halides as model halogen atom transfer precursors (initiators) and transition metal complexes as a model halogen atom transfer promoters (catalysts), a “living” radical polymerization affords (co)polymers having the predetermined number average molecular weight by &Dgr;[M]/[I]0 (up to Mn>105) and a surprisingly narrow molecular weight distribution (Mw/Mn), as low as 1.15. The participation of free radical intermediates in ATRP is supported by end-group analysis and stereochemistry of the polymerization. In addition, polymers with various topologies (e.g., block, random, star, end-functional and in-chain functional copolymers [for example, of styrene and methyl (meth)acrylate]) have been synthesized using the present process. The polymeric products encompassed by the present invention can be widely used as plastics, elastomers, adhesives, emulsifiers, thermoplastic elastomers, etc.
