ABSTRACT:
A process is described for rendering amino-group polymer solutions substantially odorless. In one embodiment, a solution of the terpolymer of vinyl pyrrolidone, vinyl caprolactam and dimethylaminoethyl methacrylate is treated with 0.1-10% by weight of an acidic compound or an acidic ion-exchange resin to render the solution substantially odorless. Other vinyl pyrrolidone polymer solutions in water and alcohol are treated similarly with equally effective results.
