The final results clearly show that the thermal steadiness of polyacrylate and polyacrylate terpolymer is healthier. Wylde et al.[79] introduced an example of the application of an ultra-high temperature antiscalant in fireplace tube heaters. They used differential scanning calorimetry to check the thermal steadiness of quite a few polymeric scale inhibitors as well as their present products and solutions. The effects show that the best thermally steady antiscalants are polymaleic acid copolymers and polymeric acrylic acids of lower to medium molecular body weight. Cenegy et al.[80] taken care of geothermal wells with a powerful degree of a scale inhibitor formulation made up of sodium acrylate/acrylamide copolymer to inhibit CaCO3 scaling in them, and proposed an exceptional formulation.
