Notes:
It was found that chloronitroso compounds with a free non-conjugated nitroso group show a considerable sensitizing activity in respect to the process of photochemical degradation of dissolved cis-1,4-polyisoprene, which is induced by visible radiation (4000-7000 A.). The effect of 10 chloronitroso sensitizing compounds were investigated. The highest sensitizing activity was found with compounds 2,2-chloronitrosopropane and 1,1-chloronitrosocyclohexane. The maximum wavelength, of which the decrease of relative viscosity of solutions was the highest, was determined for 2,2-chloronitrosopropane. The highest sensitizing activity of chloronitroso compounds was found for wavelengths corresponding to the absorption maximum of the sensitizer added. The theory of the sensitizing activity of chloronitroso compounds is proposed.
