Title: Internal photoreduction and chain scission in polyvinylbenzophenone
Abstract: Irradiation of polyvinylbenzophenone in very dilute solution in benzene results in a clear decrease of the molecular weight. The quantum yield for chain scission has been evaluated. The chain scission has been interpreted as resulting from hydrogen abstraction from a distant unit in the polymer backbone. The effect is masked in the presence of external hydrogen donors by crosslinking and internal cyclisation.
