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 formulain-line-formulae description="In-line Formulae" end="lead"?R-A-(EO, PO, BuO)n—X  (I),in-line-formulae description="In-line Formulae" end="tail"?whereR 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 andX 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.
