Maleic Acrylic Copolymer is a versatile material widely used in various industries due to its unique properties and diverse applications. This copolymer is synthesized by combining maleic anhydride (MA) and acrylic acid (AA) or its derivatives, resulting in a material with excellent chemical resistance, mechanical strength, and flexibility.
As an acrylate copolymer, its main way of obtaining is through radical-emulsion polymerization, with the most varied initiators, from peroxides to azo-starters. At low molecular weights, P(AA-MA) is mostly used as a dirt dispersant in low-phosphate detergent formulations, preventing the deposition of inorganic particles. Acrylic Acid/Maleic Anhydride Copolymer has a good thermal stability, being used under high temperatures, and a good compatibility and synergistic effect when used with other water treatment agents. Acrylic Acid/Maleic Anhydride Copolymer storage and transportation can be made in the form of an aqueous solution, powders, or granules. In the first one, it is usually done in drums, in the others, in bags.

Commercial Forms and Applications:
The uses and applications of Acrylic Maleic Copolymer may vary according to the product grade. The main forms of Acrylic Maleic Copolymer are: aqueous solution and granules. Moreover, the copolymer can be sold with several different specifications, depending on three main properties: molecular weight, AA:MA ratio, and degree of neutralization (before or after polymerization). Physical properties of the copolymer, such as molecular weight, can be varied with comonomers, composition, use of additives, and polymerization process, to give a variety of applications.
Basically, very high-MW compounds are used as flocculants, thickeners, and in superabsorbent products. Lower-MW compounds are mainly used as dispersing agents (e.g., in detergents). Industrially, Acrylic Acid/Maleic Anhydride Copolymer can also be applied in the following areas: paints and coatings; paper industry; adhesives and sealing; textile industry; and leather industry. Due to its excellent scale inhibition performance and high temperature resistance, it is widely used in various circulating cooling water systems, such as low-pressure boilers, centralized heating, and central air conditioning systems. In addition, P(AA-MA) can be used as a chelating dispersant in the textile printing and dyeing industry.

Copolymer of Maleic and Acrylic Acid has good compatibility when used together with other agents.
Environmental and Economic Significance:
Maleic Acrylic Copolymer not only offers impressive technical properties but also contributes to environmental and economic benefits. Its durability and resistance to chemicals mean that products made from this material have a longer lifespan, reducing the need for frequent replacements and thus minimizing waste.
Moreover, the versatility of Maleic Acrylic Copolymer allows for its use in multiple industries, promoting economic efficiency. Manufacturers can rely on a single material for various applications, reducing the complexity and cost of production.
Safety & Regulatory Considerations:
It is generally safe but avoid contact with eyes and prolonged contact with skin. Do not take. it internally. In case of contact with skin and eyes, wash with plenty of water.
