    摘要: The invention encompasses a composition of vinyl compounds, comprising a) at least one polymerizable compound which has at least one O-vinyl group or one N-vinyl group, and b) at least one ammonium salt of the formula (I) where R is NH2, O− NH4+, C1-C18-alkyl, C6-C18-cycloalkyl, or C7-C18-alkylcycloalkyl. The invention further relates to the use of an ammonium salt of the formula (I) as additive to polymerizable compounds which have at least one O-vinyl group or one N-vinyl group, and also to a process for inhibiting premature polymerization of compositions which comprise polymerizable compounds which have at least one O-vinyl group or one N-vinyl group, which encompasses adding to the compositions an ammonium salt of the formula (I).

    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.
