Effect of Nitro Compounds on Diene Polymers in Photodegradation

Abstract

It was investigated that photodegradation of dienepolymer in solution system by influence of Nitrosensitizer. Sensitizer was Naphthalene without Nitro again as a comparison by 1-Nitronaphthalene where luminescence was shown by ultraviolet rays in it and 1,5-Dinitronaphthalene was used and under violet irradiation by a mercury lamp. The reaction progressed easily by adding Nitrosensitizer, and IR became various in a short time on organic solvents with a meltable low molecular weight fall. Then, It was investigated the decrease in the dienepolymer molecular weight, along FT-IR and NMR of the irradiated polymers.
