  • Polymerizable pyrrolidonyl oxazoline monomers
    Patent number: 4981974
    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 consolutes.
    Type: Grant
    Filed: March 19, 1990
    Date of Patent: January 1, 1991
    Assignee: GAF Chemicals Corporation
    Inventors: Gary . Dandreaux, Robert B. Login, John J. Merianos, Paul Garelick, Krystyna Plochocka, Max Negrin, Jenn S. Shih
  • Antimicrobial polymeric bisbiguanides
