Products Description of MAA CAS#79-41-4

Methacrylic acid is an important chemical raw material. It has two functional groups, carbon-carbon double bonds and carboxylic acid groups, so it can undergo reactions such as polymerization and esterification. It can be used with Chemicalbook to prepare methyl methacrylate, coatings, synthetic rubber, adhesives, fabric treatment agents, resins, polymer material additives and functional polymer materials, etc.
