  • Novel polymeric compounds, processes and methods of use
    Patent number: 4370443
    Abstract: Water-soluble triazine-nucleated polymeric quaternary ammonium compounds, which are prepared by the interaction of 2,4,6-trichloro-1,3,5-triazine with one molecular proportion of an aliphatic or cycloaliphatic diamine containing at least one tertiary nitrogen atom capable of being quaternized to effect polymerisation and then with a second molecular equivalent of the same diamine or a different amine, are useful as mordants for water-soluble dyestuffs on cellulosic fibers; as fixing agents for pigments on cellulosic fibers; as softening agents for fibers; and as surface active agents for effecting aqueous dispersions of pigments and of colorless dyestuff precursors for carbonless duplicating systems.
    Type: Grant
    Filed: January 11, 1982
    Date of Patent: January 25, 1983
    Assignee: Sterling Drug Inc.
