Abstract

High polymer solutions having an extremely increased drag, which are characterized in that they contain additionally one or several completely soluble or miscible compounds, that have a molecular weight of less than 500,000 and increase the viscosity of the high polymer solution to a value of 10.sup.5 Pa.s.
