Abstract

Dibromo derivatives of p-substituted dibenzoylmethanes have been prepared. Elucidation of the fragmentation mechanism on continuous irradiation has shown that homolytic fragmentation of the C-Br bond is produced. The quantum yields for chromophore destruction are high and are indicative of high rates of radical production. A photocalorimetric and real time IR (RTIR) study of radical polymerization of acrylic monomers has shown that these compounds are excellent photoinitiators, the bromine radical being the initiating species.
