• The photosensitized polymerization of AN in DMF by acriflavine and stannous chloride in vacuo was investigated. The reaction rate was shown as: ν∝[D]<SUP>1⁄2</SUP>[SnCl<SUB>2</SUB>] [M]<SUP>2</SUP>, where [D] and [SnCl<SUB>2</SUB>] were small. The experiments performed examining the photobleaching of dyestuff in various conditions led to the finding that the photopolymerization does not occur by virtue of the transiently-reduced dye. The scheme proposed in Part I, in which the transient tin ion of odd valency (Sn<SUP>3+</SUP> and/or Sn<SUP>+</SUP>) initiates the polymerization by interacting with the monomer, was further substantiated.
