Polyquaternary Ammonium Patents (Class 564/295)
  • Patent number: 4271053
    Abstract: This invention relates to quaternary ammonium graft copolymers comprised of polymeric units characterized by the general formula: ##STR1## wherein n, y and z represent the relative molar equivalent fractions of each of the respective polymeric units in the graft copolymer, the sum of n, y and z being 1.0, the value of n varying from 0.00 to 0.99, the value of y varying from 0.00 to 0.99 and the value of z varying from 0.01 to 0.

  • Patent number: 4259217
    Abstract: Laundry detergent compositions containing no phosphate or low levels of phosphate materials and specific mixtures of selected nonionic surfactants and selected cationic surfactants are disclosed. The nonionic/cationic surfactant mixtures are formulated to have "cloud point" characteristics and, preferably, reduced cationic monomer concentrations as defined herein. These compositions are unusually effective in removing greasy and oily soils and body soils from fabrics; they are also effective in the removal of particulate soils. A process is disclosed for laundering fabrics using compositions containing nonionic surfactants and cationic surfactants.

  • Patent number: 4250112
    Abstract: Water-soluble polyalkylenepolyamines which are not self-crosslinking and contain quaternary dialkylammonium groups, and which are obtained by reaction of polyalkylenepolyamines of the general formula ##STR1## in which R denotes hydrogen or methyl,y denotes the number 0 or 1 and the y's may be identical or different andx denotes a number from 2 to 15,with bifunctional compounds of the general formula ##STR2## in which z denotes a number from 1 to 6 andR.sub.1 and R.sub.2 denote lower alkyl or lower hydroxyalkyl, are suitable for use as auxiliaries in the manufacture of paper.
