Methyl Vinyl Ether/Maleic Acid Copolymer
Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6) is a synthetic copolymer of methyl vinyl ether and maleic acid (or its anhydride derivatives) used widely as a functional modifier. The polymer (repeat unit formula (C7H10O5)n) provides thickening, film‑forming, dispersing and adhesion‑promoting properties in coatings, adhesives, personal care, pharmaceutical and paper applications. It is valued for good water solubility (or dispersibility in neutralized form), strong substrate binding and the ability to stabilize particle dispersions and emulsions.

1. Functions as a dispersant and stabilizer in pigment pastes and waterborne coatings, improving pigment wetting, reducing flocculation and enhancing color strength and gloss. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6).
2. Acts as a film former and adhesion promoter in adhesives and coatings, providing good substrate wetting and strong binding to polar surfaces such as paper, glass and metal oxides. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6).
3. Serves as a rheology modifier and thickener in personal care and pharmaceutical formulations when neutralized, offering shear‑thinning behavior and stable viscosity control. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6).
4. Useful in paper sizing and surface treatment to impart improved printability, ink holdout and resistance to cockling by modifying surface energy and film integrity. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6).
5. Employed in microencapsulation and controlled‑release systems as a water‑soluble matrix polymer; its acid groups allow pH‑responsive release and tailored solubility. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6).
6. Supplied as a powder with recommended neutralization and dissolution guidance; KieRay Chem provides technical support on selecting the right grade (molecular weight/acid content) and on processing to achieve optimal dispersion, film formation and performance. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Methyl Vinyl Ether–Maleic Acid Copolymer (CAS 25153-40-6).
