PROCESS TO OBTAIN RANDOM TERPOLYMERS DERIVED FROM ITACONIC ACID, ACONITIC ACID AND/OR ITS ISOMERS, AND ALKENYL SULFONATES AND USE OF THE PRODUCT THEREOF

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.
