<p>A process is described for rendering amino-group-containing polymer solutions substantially odorless. A solution of the terpolymer of vinyl pyrrolidone, vinyl caprolactam and dimethylaminoethyl methacrylate, for example, is treated with 0.1-10 % by weight of an acidic compound, or an acidic ion-exchange resin, to render the solution substantially odorless.</p> |
