Process for producing long-shelf-life aqueous solutions of vinyl-amine-unit-containing polymers and use of such solutions |
| 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. |
