Abstract

Novel donor-acceptor initiators, ′onium butyltriphenylborates, containing both an ′onium cation (electron-accepting radical generator) and a butyltriphenylborate anion (electron-donating radical generator) within the same molecule, are synthesized and investigated for the photopolymerization of an acrylic monomer mixture.
