Product Description
Poly(ethyl vinyl ethers) CAS 25104-37-4 (Lutonal A25 / A50 Analog)
Product Introduction
Poly(ethyl vinyl ethers) (CAS 25104-37-4) is a high-performance polymer available in varying molecular weights, analogous to the renowned Lutonal A25 and Lutonal A50 product lines. This versatile polymer is synthesized through controlled cationic polymerization of ethyl vinyl ethers monomers, resulting in materials with exceptional solubility, adhesive properties, and chemical stability. Our product serves as a direct alternative to traditional Lutonal formulations, offering consistent quality and reliable performance across industrial applications.
