  • Publication number: 20140206251
    Abstract: The present invention relates to surface modifying agents for polymeric and/or textile materials, methods of making and/or using a surface modifying agent to modify and functionalize polymeric and/or textile materials, and/or methods of using surface modified or functionalized polymeric and textile materials, and/or products using or incorporating surface modified or functionalized polymeric and textile materials. For example, the surface modifying agent in precursor form can be styrene sulfonyl azide monomer, polymer or copolymer capable of undergoing a chemical reaction in the presence of heat or light to form one or more styrene sulfonated nitrene monomers, polymers or copolymers, which are capable of chemically reacting with the surface of a polymeric or textile material to endow a specific or desired chemical surface functionality to the surface of a polymeric or textile material.

  • Publication number: 20140166587
    Abstract: Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a tailing solution.
