    摘要: A process for preparing addition polymers which contain carbamate units comprises reacting polyethyleneimines or addition polymers which contain vinylamine units of the formula where R1 is hydrogen or C1-C6-alkyl, with haloformic esters, the carbamate-functionalized polyethyleneimine or vinylamine polymers thus obtainable being useful as retention, drainage and flocculation aids and as fixatives in papermaking, as protective colloids for the preparation of aqueous alkyldiketene dispersions and as dispersants for the preparation of aqueous filler slurries.
