摘　　要：Ｃ６０敏化的顺１，４聚丁二烯的光氧化周涛陈双基（信阳师范学院化学系河南４６４０００）（北京大学分校化学系北京１０００８３）李子臣周锡煌李福绵（北京大学化学系北京１００８７１）关键词Ｃ６０，顺１，４聚丁二烯，光氧化自从能以宏观量制备Ｃ６０...The photo oxidation of cis 1,4 polybutadiene in the presence of C 60 was studied by pursuing the IR spectra changes with irradiation time and determination of the peroxide with spectrometric method.It was found that C 60 acted as a effective photosensitizer to convert the molecular oxygen into singlet oxygen and thus the ene reaction of singlet oxygen with carbon carbon double bonds in the polymer chain took place.The content of peroxide formed increased with the increase of the irradiation time and the concentration of C 60 ,but seemed to have little relation with the concentration of cis 1,4 polybutadiene under current experimental conditions.Isomerization of double bonds with little carbony group formation were also observed during the photo oxidation.
