Diacid Monomers

Diacid monomers, also known as dicarboxylic acids, typically appear as white crystalline solids or powders. Functionally, diacid monomers are essential in the production of polyesters and polyamides, where they react with diols or diamines to form long polymer chains. Key features include excellent thermal stability, mechanical strength, and resistance to chemicals, making them suitable for applications in textiles, automotive parts, and packaging. 

Alternatives to diacid monomers include anhydrides and multifunctional acids. Sub-types include aromatic diacids like terephthalic acid and aliphatic diacids like adipic acid.
