  • Patent number: 11384187
    Abstract: The present invention is related to the process of obtaining random terpolymers based on itaconic acid or its isomers, aconitic acid or their isomers and sodium alkenyl sulphonates, through a polymerization in aqueous solution, via free radicals at acid pH in the range of 1.0 to 3.5 and as initiator a redox system. The random terpolymers are characterized for being tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium. Their use as inhibitors of mineral scale such as calcium carbonate, calcium sulphate, strontium and barium, and clay dispersing, iron oxides, carbonate and calcium sulfate allows for their application in the reservoir or production rig, treated water, sea water and/or connate water can be used as means of transportation. The terpolymer can be used to inhibit and disperse mineral scales present in cooling system and boiler employed in the chemical and oil industry, and is compliant with environmental standards established internationally.
