A process is disclosed for preparing aqueous solutions of poly(N-vinyl- epsilon -caprolactam) by polymerising poly(N-vinyl- epsilon -caprolactam) in an aqueous medium in the presence of polymerisation initiators and 0.1 to 20 % by weight, in relation to the monomers used, of a water-soluble, polymer protective colloid. The thus obtained aqueous polymer solutions are useful as textile printing glues, raw materials for glues, lubricant additives, vehicles for cosmetic compositions, additives for washing products and as opacifiers in automatic shading systems. |
