  • Patent number: 10472484
    Abstract: Molecularly imprinted polymers (MIPs) are materials exhibiting molecular recognition of a target molecule. MIPs are synthesized in the presence of an aflatoxin template, a mimic to the targeted molecule, used as an imprint that is further washed away with suitable solvent after completion of the polymerization process, leaving a cavity in the polymer of the same stereochemistry, functionality and morphology to the template. When the MIP encounters an aflatoxin, the molecule is bound in the cavity with a receptor-like affinity.

  • Patent number: 8940845
    Abstract: The invention provides a novel method for producing a water-absorbent resin comprising: subjecting at least one water-soluble ethylenic unsaturated monomer to reversed-phase suspension polymerization in a petroleum hydrocarbon dispersion medium, the reversed-phase suspension polymerization being conducted using a 0.00005 to 0.00016 mole of water-soluble azo initiator for radical polymerization per mole of the water-soluble ethylenic unsaturated monomer in the presence of 0.000015 to 0.00015 mole of hypophosphorous compound per mole of the water-soluble ethylenic unsaturated monomer. According to the method, the environmental impact can be lessened by reducing the amount of petroleum hydrocarbon dispersion medium released to the outside of the system, and the method makes it possible to obtain a water-absorbent resin having a high water-retention capacity and water-absorption capacity under a load, and a small content of water soluble component at the same time.

  • Publication number: 20080242791
    Abstract: The present invention relates to the use of poly acrylic and/or methacrylic macroinitiators in the free radical addition reaction of vinyl aromatic monomers to improve the properties of the resulting copolymer and/or composite. More particularly, the present invention relates to the production of poly acrylic and/or poly methacrylic macroinitiators having nitroxyl end groups. Using such macroinitiators in the free radical addition reaction of vinyl aromatics such as polystyrene compatibilizes the acrylic monomer in the vinyl aromatic matrix thereby improving the properties of the resulting polymer.

  • Patent number: 6849701
    Abstract: A droplet polymerization process is provided to create efficacious molecularly imprinted polymers (MIPs). Such imprinted polymers have increased surface area for adsorptive or catalytic reactions. This method provides for monomer-template interactions in the absence of a suspending medium, thereby permitting formation of MIPs with increased template selectivity and substantial processing advantages. The process is particularly useful for separating isoflavones from soy whey.
