Properties of Poly (methyl vinyl ether-alt-maleic acid) CAS 25153-40-6

PVM/MA is a thermoplastic elastomer that exhibits a unique combination of properties. It has a glass transition temperature (Tg) of approximately -60°C, which allows it to be processed at temperatures above its Tg. The chemical structure of PVM/MA contributes to its excellent adhesion to a wide range of substrates, including metals, glass, and plastics. Additionally, PVM/MA possesses good chemical resistance, making it suitable for applications in harsh environments.

The physical properties of PVM/MA can be tailored by adjusting the ratio of MVE to maleic acid in the polymer. This allows for the creation of materials with varying degrees of flexibility, toughness, and adhesion. The presence of maleic acid in the polymer chain also imparts hydrophilic properties, which can be beneficial in certain applications.

Synthesis of Poly (methyl vinyl ether-alt-maleic acid) CAS 25153-40-6

The synthesis of PVM/MA involves the copolymerization of MVE and maleic anhydride or maleic acid.
