poly(methyl methacrylate-co-maleic anhydride)

Synthesis and Application of Macrophotoinitiators Obtained via Benzoin Tethering with Copolymers of Maleic Anhydride

A new approach to the synthesis of macrophotoinitiators (MPI) on the basis of benzoin was developed; it was grounded on the tethering of benzoin to copolymers of methyl methacrylate and maleic anhydride. This process occurred as a polymer-modification reaction due to interaction of the anhydride groups in polymer structure with hydroxyl functionality of benzoin and resulted in formation of benzoin monomaleate units. Chemical structure of MPI and content of benzoin moieties tethered were determined using IR- and UV-spectroscopies.
