  • Preparation of discrete microdroplets of a high viscosity oil in water
    Patent number: 5084208
    Abstract: What is provided herein is a method for preparing discrete microdroplets of a high viscosity oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer. The method comprises dispersing the oil in water containing a surfactant, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, optionally with a comonomer, and polymerizing the monomer or comonomers in situ such that the oil is stabilized in the resulting polymer solution as discete microdroplets.
    Type: Grant

  • Poly(pyrrolidonyl oxazoline)
    Patent number: 5008367
    Abstract: What is described herein are polymerizable pyrrolidonyl 4,5-unsubstituted oxazoline monomers, homopolymers thereof, and copolymers with other monomers. A preferred polymerizable monomer compound is 2-(1-methyl-2-pyrrolidon-4-yl)-2-oxazoline. The polymers herein have excellent hydrotropic properties thus increasing the water solubility of organic compounds previously considered as water insoluble, and exhibit complexation with water soluble cosolutes.
