摘要
成功地合成了三种稀土硬脂酸盐(CeSt3、NdSt3及PrSt2)络合光敏剂。用元素分析和IR表征了这些光敏剂。采用测试LDPE膜的力学性能、红外羰基指数(CI=A1714cm-1/A1377cm-1)以及测定膜的粘均分子量的方法,研究并比较了这几种稀土光敏剂引发LDPE膜紫外光降解的效果。
Three photosensitizers containing rare earth stearate complex compounds (CeSt3,NdSt3 and PrSt2) were successfully synthesized These photosensitizers were characterized with fluorescent spectrograph and IR spectrograph During the UV oxidation degradation,the photodegradable property of the LDPE film containing only certain one of these additives was studied and compared by testing their mechanical properties,carboxyl indices (CI=A1714cm-1/A1377cm-1) and viscosity average molecular weights.
