Abstract

Compositions are provided that include an electron donor and a sensitizing compound. More specifically, the electron donor is an arylsulfinate salt. Methods of polymerization are also provided that can be used to prepare polymeric material from a photopolymerizable composition that includes ethylenically unsaturated monomers and a photoinitiator system. The photoinitiator system includes an electron donor and a sensitizing compound.
