Popis

Application

2,2-Dimethoxy-2-phenylacetophenone (DMPA) can be used as a photoinitiator:

• For the photopolymerization of methacrylate monomers in thick sections(~2mm).
• In the preparation of UV-curing silicone rubber with excellent mechanical properties and thermal stability via thiol-ene reaction.

It can also be used as a starting material to prepare a water-soluble supramolecular-structured photoinitiator which is more efficient than DMPA.
