Poly(methyl vinyl ether-alt-maleic anhydride)(CAS: 9011-16-9)

Poly(methyl vinyl ether-alt-maleic anhydride) (PVM/MA) is a copolymer with a molecular weight ranging from 1,000 to 100,000. It is sparingly soluble in water but soluble in organic solvents. The polymer exhibits good reactivity due to the presence of carboxylic acid groups from maleic anhydride. It is often used in applications requiring controlled polymerization and high functionality.

Poly(methyl vinyl ether-alt-maleic anhydride) (PVM/MA) is synthesized via anionic copolymerization of methyl vinyl ether (MVE) and maleic anhydride (MA). Common catalysts include organometallic compounds like lithium dialkylcuprate. The reaction involves the sequential addition of monomers, leading to a copolymer with alternating units of MVE and MA, achieving high selectivity and good yield.

Poly(methyl vinyl ether-alt-maleic anhydride) (PVM/MA) finds application in pharmaceuticals for controlled drug delivery systems, in polymers for enhancing adhesion and durability, in sensors for improved sensitivity, and in semiconductors for surface modification and etching processes.

When handling Poly(methyl vinyl ether-alt-maleic anhydride) (PVM/MA), it is crucial to use personal protective equipment (PPE) such as gloves, goggles, and lab coats. Work in a well-ventilated area or fume hood. In case of spill, neutralize with a base, then clean with water. Refer to the Safety Data Sheet (SDS) for detailed emergency response procedures and storage guidelines.
