Abstract

A polyvinyl alcohol gel can be easily and quickly produced by a process having the following steps: (a) use of an aqueous polyvinyl alcohol solution with a degree of hydrolysis (98 % by moles; (b) admixture of an additive that is dissolved in the aqueous polyvinyl alcohol solution and forms a separate, finely distributed and aqueous phase after concentration of the solution; (c) drying of the aqueous solution to a residual water content of maximum 50 wt. % to cause the phases to separate and hence the polyvinyl alcohol to gel; (d) rehydrating the polyvinyl alcohol in an aqueous medium. 25 claims
