【摘要】 合成了以二硫代氨基甲酸为配体的一系列铁络合物以及硬脂酸铁光敏剂。通过人工加速紫外光降解试验和自然暴露试验,研究了含光敏剂的LDPE膜的力学性能、粘均分子量、红外线吸收及羰基指数的变化,比较讨论含上述铁盐光敏剂的LDPE的光降解性能更多还原

【Abstract】 Some photosensitizers containing ferric complex were successfully synthesized, such as ferric N, N dialkyl dithio carbamate (FeDRC) and ferric stearate (FeSt 3). The effect FeDRC and FeSt 3 on mechanical properties, carboxyl index and viscosity average molecular weight of LDPE films has been studied and compared during the UV oxidation degradation.更多还原
