Abstract
An aqueous solution of poly(N-vinyl-.di-elect cons.-caprolactam) is prepared by polymerizing N-vinyl-.di-elect cons.-caprolactam in an aqueous medium in the presence of a polymerization initiator and from 0.1 to 20% by weight, based on the monomer used, of a water-soluble polymeric protective colloid and is useful as a textile printing adhesive, as a raw material for adhesives, as a lubricant additive, as a cosmetic formulation aid, as a detergent additive and as an opacifier in automatic shading systems.
