一般說明

甲基丙烯酸（MAA）是一种有机化合物，无色，粘性液体。它是一种单功能甲基丙烯醛单体。它在温水中可溶解，可以和大多数有机溶剂混合。MAA可用作对应酯化产物的起始物质；尤其是甲基丙烯酸甲酯与聚甲基丙烯酸甲酯（PMMA）。

應用

MAA可用于合成聚（甲基丙烯酸）-g-聚(ε己内酯）共聚物，和PMMA以及甲基丙烯酸羟乙酯（HEMA）-MAA凝胶聚合共混合。

Continuous Flow Manufacturing for Monomer Synthesis

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
