摘要: Use of cross-linked polymers for increasing the viscosity in cosmetic, pharmaceutical and technical compositions, wherein polymer chains have following composition: k - p molar % groups formula ##STR1## ##STR2## from 0 to 45 ##STR3## 0.1 20 a cross-linking agent, R 1 represents as statistical mean value 100 hydrogen %, each calculated on proportion (k-p) CH 2 OH groups, 3 are hydrogen, or one radicals is methyl, other being X cyano, alkoxycarbonyl with 8 carbon atoms altogether, whose alkoxy radical may also be substituted by --OH, alkanoyloxy 6 atoms, alkanoylamino which--if they at least 4 atoms--may cyclic then form pyrrolidone caprolactam ring, phenyl, carboxyl trialkoxysilyl M an alkali metal cation, stands range 99.9 50, 5 k, said products prepared copolymerizing, total amount all monomers, acrylamide, defined above, compound I ##STR4## which , agent presence initiator water-miscible alkanol, mixing dispersion obtained under action strong shearing forces hydroxide MOH, heating mixture temperature 30 150° C. up saponification amide --COOM-- either isolating copolymer methylolating same, after removing ammonia, lower alkanol paraformaldehyde, 10° boiling point employed.
