  • Imidazolinone-containing copolymer
    Patent number: 4785070
    Abstract: A novel class of heterocyclic polymers and copolymers containing the 2-imidazolin-5-one ring structure is described. These polymers are prepared by reaction of bisazlactones and diamines, with or without suitable condensation monomers; the resultant polyamides are then thermally cyclodehydrated in the presence of a catalyst to produce the imidazolinone-containing polymers. Many of the poly(imidazolinones) are water soluble and therefore find utility in various aspects of water treatment, or in paper or fabric sizing.
    Type: Grant
    Filed: February 17, 1987
    Date of Patent: November 15, 1988
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Jerald K. Rasmussen, Alan R. Katritzky, Larry R. Krepski, Howell K. Smith, II, Steven M. Heilmann, Kumars Sakizadeh
