    Abstract: Ophthalmic lenses, such as intraocular lenses, include cross-linked polymeric materials having a first constituent derived from a first monomeric component selected from the group consisting of acrylates, methacrylates and mixtures thereof, and a second constituent derived from a second component in an amount effective as a cross linker in the cross-linked polymeric material. The cross-linked polymeric material has branched chain alkyl groups, preferably included with at least a portion of the first monomeric component, in an amount effective to reduce the tackiness of the cross-linked polymeric material relative to a substantially identical cross-linked polymeric material without the branched chain alkyl groups.

  • Patent number: 6667374
    Abstract: A high molecular weight water soluble acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepared by a process in which a small quantity of a chain branching agent is added to the polymerization reaction mixture continuously or stepwise while the monomers are polymerized. The polymer is useful in solid/liquid separations such as flocculants and coagulants in wastewater treatment applications, and as thickening agents.

    Abstract: A process is disclosed for a continuous, high temperature polymerization process for preparing a free radically polymerized epoxy-functional polymeric product. The process comprises continuously charging into a reactor at least one epoxy-functional acrylic monomer, and optionally at least one non-functional free radical polymerizable monomer. An optional free radical polymerization initiator may also be added. The reactor is maintained at an effective temperature for an effective period of time to cause polymerization of the monomers into a polymeric product, such that the polymeric product is formed substantially free of gel particles. A clear coating is also disclosed incorporating polymers of the present invention, such that the clear coating has a low Delta b value at standard conditions.

  • Patent number: 6616825
    Abstract: An electrochromatographic device is provided for conducting enantioselective separation of enantiomers. The device is comprised of a conduit containing a monolithic enantioselective separation medium, and may be, for example, a capillary tube or a microchannel in a substrate. The enantioselective separation medium is prepared by copolymerization of (a1) an ionizable chiral monomer or (a2) a chiral monomer and an ionizable comonomer, along with (b) a crosslinking comonomer and (c) a polymerization initiator, in (d) a porogenic solvent. Following ionization, the enantioselective separation medium serves as a charge carrier as well as a chiral separation medium, and further acts as an electroosmotic pump to facilitate the flow of a fluid. The invention also provides methods for preparing the enantioselective separation medium and electrochromatographic devices fabricated therewith.
