Abstract
Methacrylic acid was photopolymerised using CdS and composite, CdS/HgS and CdS/TiO2, Colloidal semiconductor particles as initiators. The pr eviously proposed photoinitiation mechanism involving the photogenerat ed positive hole in the valence band of the CdS colloid was confirmed by the electron scavenging action of TiO2. The effect of pH on the cou rse of the polymerisation was investigated and is discussed.
