Abstract: Fatty acid esters of hydroxyalkyl sulfonates are prepared by heating an excess of the fatty acids with the sulfonate until the water of condensation is removed. The hot crude ester is then quenched by immersion in an excess of cooled liquid, in which the ester product is soluble but in which unreacted, excess fatty acids are insoluble. The resulting slurry is filtered to separate the relatively pure ester from the quenching liquid containing dissolved free fatty acid. Isopropanol is the preferred quenching liquid.

Abstract: There is disclosed a process for the aqueous solution or emulsion polymerization of acrylamide monomer to produce homopolymers of very high molecular weight using mixtures of water and monomer at least one of which can be contaminated with small amounts of polymerization inhibiting components. In the process, a minimum effective amount of a redox catalyst is utilized in order to obtain very high molecular weight by incrementally adding one member of a redox pair to a solution of the monomer containing a second redox pair number.

Utilizing monomer concentrations of about 10 to about 50 percent by weight, molecular weights of about 1,000,000 to 10,000,000 can be obtained.
