  • Patent number: 7687601
    Abstract: Conductive polymers are purified using a solid scavenger. The solid scavengers include metal-scavenging functional groups linked to the surface of a particle support material. To improve the functionalization of the support material, the support materials are first treated with sulfuric acid or nitric acid before attaching the molecules containing the metal-scavenging functional groups. The solid scavengers used in the purification methods are more efficient at removing impurities in conductive polymers than existing scavengers.

  • Patent number: 6590042
    Abstract: A process for reclaiming sulfur-cured, vulcanized rubber by combining finely ground scrap vulcanized rubber within a specialized, twin-screw extruder capable of providing strong shearing and just-on-time mixing; adding a reclaiming agent to the extruder; and masticating the rubber scrap and reclaiming agent within the extruder until the rubber scrap is devulcanized. The present invention also discloses a unique composition of reclaiming agent, which preferably includes the following compounds: accelerators TBBS, ZMBT, MBT, and TMTM; activators zinc oxide and stearic acid; and zinc salts of fatty acids and sulfur. The reclaimed rubber is suitable for use in producing high-grade, rubber products without adding a binder, or for combining with fresh rubber compounds to produce high-specification rubber products.

  • Patent number: 6573337
    Abstract: The invention provides a system for solid-phase synthesis of oligosaccharides, based on the discovery that a 2-substituted-1,3-dioxocycloalkyl linker group of general formula (I) can be used to couple saccharide groups of both the O-glycoside and N-glycoside type to a polymer support. The invention provides reagents, reagent kits and methods for solid-phase oligosaccharide synthesis.

  • Publication number: 20030044378
    Abstract: Method for preparing biocidal halogenated polystyrene hydantoins. The biocidal polymers poly-1,3-dichloro-5-methyl-5-(4′-vinylphenyl)hydantoin, poly-1,3-dibromo-5-methyl-5-(4′-vinylphenyl)hydantoin, and their monohalogenated alkali metal salts and protonated derivatives have been prepared as porous beads by use of highly crosslinked polystyrene beads as starting materials. The porous beads will be useful in water and air disinfection applications when employed in cartridge filters and carafes (for water), as well as for controlling noxious odor when mixed with absorbent materials in items such as disposable diapers, incontinence pads, bandages, sanitary napkins, pantiliners, mattress covers, shoe inserts, sponges, animal litter, carpets, fabrics, and air filters or the like.

  • Patent number: 6462139
    Abstract: Film-forming compositions which are substantially free of organic solvent and capable of forming a generally continuous film at ambient temperature are provided. The film-forming composition includes at least one thermosettable aqueous dispersion of polymeric microparticles having functionality adapted to react with a crosslinking agent. The polymeric microparticles are prepared by mixing under high shear conditions (1) at least one hydrophobic polymer having reactive functional groups; and (2) at least one hydrophobic crosslinking agent containing functional groups which are reactive with the functional groups of the polymer. Further provided is a multi-component composite coating composition which includes a pigmented base coat and a transparent topcoat of the substantially organic solvent-free film-forming composition described above. Substrates coated with the same are also provided. Additionally, a method for preparing the aqueous dispersion of polymeric microparticles is provided.

  • Patent number: 6437051
    Abstract: The present invention provides a graft copolymer of a syndiotactic styrene/para-alkylstyrene copolymer, having the formula of wherein R1 and R2 are independently selected from the group consisting of hydrogen, alkyl, and primary and secondary haloalkyl; X is a functional group selected from a group containing halogen, oxygen, sulfur, silicon, nitrogen, carbon, phosphorus, and mixtures thereof; Y is an atactic polymer moiety; a ranges from 10 to 30000; b ranges from 0 to 30000; c ranges from 0 to 30000; and d ranges from 1 to 30000. The compatibility of the graft copolymer of syndiotactic styrene/para-alkylstyrene copolymer of the present invention with other polymers is improved over a syndiotactic styrene polymer. Also, the graft copolymer of the present invention can serve as a compatibilizer for a polymer blend.
