METHOD FOR OBTAINING RANDOM TERPOLYMERS DERIVED FROM ITACONIC ACID AND ACONITIC ACID, AND/OR THE ISOMERS THEREOF, AND/OR SODIUM ALKENYL SULPHONATES, AND USE OF THE RESULTING PRODUCT |
摘要 |
The invention relates to random terpolymers based on itaconic acid, aconitic acid and sodium alkenyl sulphates, prepared by means of polymerisation in an aqueous solution using free radicals at an acid pH in the range of 1.0 to 3.5, with a redox system as an indicator. Said terpolymers act as inhibitors of mineral scaling, such as calcium carbonate, calcium sulphates, strontium and barium, and dispersants of clays, iron oxides, carbonates and calcium sulphate. |
