摘要

P THE INVENTION CONCERNS STABLE DISPERSIONS, WATER IN OIL OF WATER-SOLUBLE CATIONIC POLYMERS BASED ON DIMETHYLAMINOETHYL ACRYLATE, SALIFIED OR QUATERNIZED, COPOLYMERIZED OR NOT WITH ACRYLAMIDE AND CONTAINING MORE THAN 5 MOLES. NOT STATICALLY DISTRIBUTED ALONG THE CHAINS, HAVING A PONDERAL COMPOSITION OF 20 TO 55 IN POLYMERS, FROM 20 TO 45 OF OIL, FROM 1 TO 5 AT LEAST TWO EMULSIFYING AGENTS AND THE COMPLEMENT TO 100 OF WATER, THE OIL PHASE BEING A MIXTURE OF NORMAL CC ALKANES, ONE OF THE EMULSIFIERS HAVING A HLB OF 3 TO 5 AND A GOOD SOLUBILITY IN THE OIL PHASE AND A LIPOPHILIC GROUPING OF A BRANCHED CARBON CHAIN OF AT LEAST 16C, AND THE OTHER HAVING A AVERAGE HLB FROM 12 TO 16, THE PERCENTAL PERCENTAGES OF THE TWO AGENTS BEING 0.5 TO 3 RELATIVE TO THE WEIGHT OF THE DISPERSION. /P
