  • Use of polymers containing vinylamine units as promoters for alkyldiketene glueing
    Publication number: 20060162883
    Abstract: The invention relates to the use of polymers containing vinylamine units having a K-value (determined in 5% of an aqueous sodium chloride solution and at a temperature of 25%, having a pH-value of 7, and a polymer concentration of 0.5 wt. %) of 30-150 as promoters for mass glueing of paper with alkyldiketenes.

  • Hydrophobically modified polymers containing vinylamine or ethylenimine units, method for the production thereof, and their use as retention agents
    Publication number: 20050239974
    Abstract: Hydrophobically modified polymers containing vinylamine or ethylenimine units and obtainable by reacting (a) polymers containing vinylamine or ethylenimine units with (b) compounds of the formula R-A-(EO, PO, BuO)n—X ??(I), where R is C4— to C26-alkyl or C4— to C26-alkenyl, A is O, NH or COO, EO is an ethylene oxide unit, PO is a propylene oxide unit, BuO is a butylene oxide unit, n is from 1 to 250 and X is a functional group which can be covalently bonded to an OH group, process for the preparation of hydrophobically modified polymers containing vinylamine or ethylenimine units by reacting polymers containing vinylamine or ethylenimine units with a water repellent of the formula I and use of the polymers thus obtainable as an additive to paperstock in papermaking.
