  • Novel resins
    Patent number: 3992433
    Abstract: A resin having a formula of ##SPC1##Wherein each of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 is hydrogen or methyl group, each of R.sup.7, R.sup.8, R.sup.9 and R.sup.10 is hydrogen, alkyl group having 1 to 6 carbon atoms or phenyl group and X is -CN, -CONH.sub.2, -COOM or -COOR.sup.a, M being hydrogen, -NH.sub.4 or alkali metal, R.sup.a being alkyl group having 1 to 4 carbon atoms; and a method for manufacturing the same, said resin being usable as substitutes for resin and its derivatives.
    Type: Grant
    Filed: June 23, 1975
    Date of Patent: November 16, 1976
    Assignees: Arakawa Rinsan Kagaku Kogyo Kabushiki Kaisha, Nard Institute, Ltd.
    Inventors: Junji Ariyoshi, Noboru Kariya
  • Treating agent useful for fibrous materials and preparation thereof
    Patent number: 3988503
    Abstract: Amide-containing polymer is reacted with polyalkyleneimine in an aqueous medium to form a water-soluble cationic resin which is a treating agent useful for fibrous materials. The adduct of halohydrin to the water-soluble cationic resin is a water-soluble cationic thermosetting resin and is also useful for treating fibrous materials. The treating agent has excellent retention ability to fiber, drainage property and storage stability and remarkably improves the retention of fillers and wet and dry strength of paper.
