Colour Changes

Polyvinyl bromide in solution, in dry tetrahydrofuran (THF) yields a black polymer upon exposure to u.v. light of 260 nm or less. This is shown to be the result of ( a ) the elimination of bromine atoms in the primary reaction, and ( b ) the catalysed formation of a conjugated chain by the eliminated bromine atoms. The black polymer is bleached by visible light with the formation of a cross-linked product. This blackening takes place in the full light of the mercury lamp, but by the introduction of a suitable filter passing only visible light, the colour changes can be arrested and ultimately reversed though the viscosity continues to increase due to cross-linking. In dry solutions the liberated bromine is absorbed by the THF solvent and no free Br 2 or HBr is produced. In the presence of water, the products are completely changed. No blackening occurs, free HBr is eliminated, and the colourless PVB becomes cross-linked and ultimately yields a gel. On irradiating the black polymer in aqueous THF by visible light, it becomes bleached, yielding a cross-linked colourless polymer which ultimately gels.
