  • Patent number: 10287376
    Abstract: A method for producing an amphiphilic particle or an anisotropic particle includes combining seed particles with a monomer emulsion to obtain monomer-swollen seed particles, polymerizing the monomer-swollen seed particles to obtain polymerized monomer-swollen particles, and hydrolyzing the polymerized monomer-swollen particles. An amphiphilic particle is adapted to stabilize a first type of multiphasic mixture comprising a first aqueous phase having a first pH and a second type of multiphasic mixture comprising a second aqueous phase having a second pH.

  • Patent number: 10233211
    Abstract: The present invention relates to a selectively soluble polymer capable of binding to a desired molecules in an unclarified mixture containing various biological materials and the methods of using such a polymer to purify a molecule from such a mixture. The polymer is soluble in the mixture under a certain set of process conditions such as pH or temperature and/or salt concentration and is rendered insoluble and precipitates out of solution upon a change in the process conditions. The polymer is capable of binding to the desired molecule (protein, polypeptide, etc) and remains capable of binding to that molecule even after the polymer is precipitated out of solution. The precipitate can then be filtered out from the remainder of the stream and the desired biomolecule is recovered such as by elution and further processed.

  • Patent number: 10161140
    Abstract: A polymeric degassing primer composed of an alkali-resistant polymer having a low viscosity. The degassing primer is spread over a concrete substrate prior to applying a waterproof adhesive. The waterproof adhesive can be used to bond a flooring material to the concrete substrate coated with the degassing primer. The degassing primer penetrates and displaces air from the concrete micro-channels and pores, thereby eliminating the possibility of creating air bubbles under the flooring material.
