Abstract
A hydrophilic polymer gel can be prepared by polymerising the monomer or monomers of said polymer in an aqueous medium together with a compatible organic solvent and vinyl copolymer comprising 5 to 95 mol% of units of the general formula: < IMAGE > and, correspondingly, 95 to 5 mol% of recurring units of the formula: < IMAGE > in which R1 and R3 independently represent hydrogen or lower alkyl, R2 represents an alkyl group of at least 8 carbon atoms, and Y represents a hydrophilic radical or a quaternisable radical such as a pyridino or imidazolino radical. The method for the preparation of such gels prevents adherence of the gel particles together and so enables the complete drying of the gels.
