  • Patent number: 9630881
    Abstract: Use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of thermoset polymer particles is disclosed. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles.

  • Patent number: 7928177
    Abstract: Biocompatible polymers are manufactured to include an amino acid mimetic monomer and one or more hydrophobic acrylate monomers. The amino acid mimetic monomers are selected to mimic the side chain of the amino acids asparagine or glutamine. The amino acid mimetic monomer can be a methacryloyl or acryloyl derivative of 2-hydroxyacetamide, 3-hydroxypropionamide, alaninamide, lactamide, or glycinamide. These amide functional groups offer the advantage of moderate hydrophilicity with little chemical reactivity. The amino acid mimetic monomer can be copolymerized with one or more hydrophobic acrylate monomers to obtain desired coating properties.

  • Patent number: 7847047
    Abstract: A material which expresses its critical solution temperature even in an aqueous solution containing a buffer or salt, and at the same time, shows small variation width of the critical solution temperature even when concentration of salt or the like contained in water, a buffer liquid or the like is different, interacts with a substance such as a component in the living body and can therefore be used efficiently in the isolation of substances, is provided. A monomer represented by a formula (1) and a thermoresponsive polymer which contains said monomer as a polymerization component.
