Abstract: Proposed is the use, as agents for increasing the dry strength of paper, card and cardboard, of partially hydrolysed polymers of N-vinyl carboxylic acid amides obtained by the homopolymerization of N-vinyl carboxylic acid amides of the formula (I) in which R and R are H or C1-C6 alkyl and by splitting off 0.5 to 95 mole % of the groups of the formula (II) in which R is H or C1-C6 alkyl.

Abstract: The invention relates to a method for producing polymers containing carbamate units, wherein polyethylene imines or polymers containing vinyl amine units of formula (III) in which R = H or C1-C6-alkyl are made to react with halogen formic acid esters. The invention also relates to the use of the polyethylene imines containing carbamate groups thus obtained or polymers containing vinyl carbamate units as retention agents, dehydrating agents, flocculants and fixing agents in the production of paper, as a protective colloid for the production of aqueous alkyl diketene dispersions and as a dispersing agent for the production of accumulated aqueous filling material slurries.

Abstract: The invention concerns amphiphilic graft polymers in which the graft base is a polymer containing at least 5 wt % of units of formula (I) and optionally units of formula (II), R , R being H or C1-C6 alkyl, wherein (a) styrene, C1-C2 alkylstyrene and/or vinyltoluene and optionally (b) other monoethylenically unsaturated monomers which can be copolymerized therewith are grafted onto the graft base in a weight ratio of between 1: 99 and 99: 1, and wherein the group (c) is optionally partially or completely cleaved off the graft polymers, forming amino groups. The invention also concerns processes for preparing and using the amphiphilic graft polymers as consolidating agents for paper, as fixing agents for disruptive water-soluble and water-insoluble agents in paper manufacture, as dispersants for inorganic and organic pigments, dyes, concrete and plant-protecting agents, as detergent additives, as coating material for fertilisers and plant-protecting agents, as floor-maintenance agents, as protective colloids for aqueous polymer dispersions, as thickeners for cosmetic formulations, as conditioners for skin-care agents and as a component of hair-cosmetic preparations and cosmetic preparations for oral hygiene.
