Abstract: A process for producing long-shelf-life aqueous solutions of vinyl-amine-unit-containing polymers by the hydrolysis of N-vinyl-carbonamide-containing polymers with acids in an aqueous medium and removing the carboxylic acids separated from the polymers as esters from the aqueous polymer solution following hydrolysis and by the addition of at least stoichiometric quantities of at least one C1 to C6 alcohol and distilling the esters off from the reaction mixture. The invention also relates to the use of the long-shelf-life aqueous solutions of vinyl-amine-unit-containing polymers as dry and wet consolidating agents in paper manufacture.

Abstract: In a cationic modification process for starch, starch is reacted with polymers that contain amino and/or ammonium groups in an aqueous medium at temperatures from 115 to 180 DEG C under an increased pressure and in the absence of oxidisers, polymerisation initiators and alkali. The reaction is conducted so that maximum 10% by weight starch has its molar weight reduced. Also disclosed is the use of the thus obtained reaction products as dry strength agents for paper.

Abstract: A process for the production of stable water-in-oil emulsions of hydrolysed polymers of n-vinyl amide of formula (I) in which R, R = H or C1-C6 alkyl, by the polymerisation of compounds of formula (I) alone or mixed with other ethylenically unsaturated monomers in the presence of polymerisation initiators and emulsifiers in the form of water-in-oil emulsions to form water-in-oil polymer emulsions followed by the hydrolysis of the polymers in the form of the water-in-oil polymer emulsions in the presence of acids or bases and 1 to 30 wt % in relation to the polymers of emulsifiers, in which the emulsifiers used are mixtures of (a) 5 to 95 wt % of a block or graft copolymer of the structure (A-B)m, (A)nB or (B)nA in which A is a hydrophobic homo or copolymer with a degree of polymerisation of at least 3, B is a hydrophilic homo or copolymer with a degree of polymerisation of at least 3, m >/= 1 and n >/= 2, and (b) 5 to 95 wt % of another water-in-oil emulsifier with a molar mass of under 1000 g/mol. The polymer emulsions thus obtained may be used as retention and flocculation agents in paper production, to purify waste water and sludges in purification plants, as a dispersant and protective colloid for drilling muds and as a cement additive.

The invention further concerns polymers which contain aminal, semi-aminal and/or aminal-acetal structures and which are obtained by reacting (a) polymers containing vinylamine units with (b) compounds comprising aldehyde or keto groups and (c) compounds comprising NH groups and/or OH groups.
