Low-density polyethylene in benzene, toluene, and <I>o</I>-dichlorobenzene was irradiated by UV light to clarify the roles of solvents in the polymer photochemical degradation. Irradiation was done for 50 h at 25 and 50°C in air, oxygen, and nitrogen atmospheres. Reaction products were analyzed by FT-IR, GPC, <SUP>13</SUP>C NMR. Carbonyl groups, double bonds, and hydroperoxide groups in the polyethylene irradiated for 50 h were detected by FT-IR and <SUP>13</SUP>C NMR. The molecular weight changed a little. Quantities of the functional groups and gels increased in the order of benzene, toluene, and <I>o</I>-dichlorobenzene. Oxygen molecules play an important role in this kind of photochemical reaction.
