Abstract

Monomer acrylamide was used as quencher of uranyl ion fluorescence and Stern‐Volmer plots were constructed at three monochromatic wavelengths of exciting radiation. The results indicated that the reaction between excited uranyl ion and monomer is one of energy transfer. The rate parameters k~p~/k~p~^½^ and k~d~′/k~i~ were calculated from the polymerization kinetics at high monomer concentrations. A general mechanism for the photopolymerization of vinyl monomers sensitized by uranyl ions is proposed and discussed.
