【摘要】 利用差示扫描量热仪(DSC)研究了茂金属线性低密度聚乙烯(mLLDPE)和传统线性低密度聚乙烯(LLDPE)的非等温结晶行为。采用Jeziorny法和莫志深法对所得的数据进行了分析。结果表明,采用莫志深法处理数据可得到较好的线性关系,且mLLDPE在相同的相对结晶度下的结晶速率低于LLDPE。更多还原

【Abstract】 The nonisothermal crystallization behavior of metalloeene linear low density polyethylene(mLLDPE)and traditional linear low density polyethylene(LLDPE)was stud- ied by differential scanning calorimeter(DSC).The DSC data were analyzed by the theories of Jeziorny and Mo Zhishen.The results show that nonisotheramal crystallization results are successfully analyzed by Mo Zhishen theory,and the crystallization rate of mLLDPE is slo- wer than that of traditional LLDPE at the same relative crystallinity.更多还原
