【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。

【Abstract】 Three photosensitizers containing rare earth stearate complex compounds (CeSt3,NdSt3 and PrSt2) 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=A1714cm-1/A1377cm-1) and viscosity average molecular weights.
