| 中文摘要 | the non-isothermal crystallization behavior and kinetics of metallocene short chain branched polyethylene were investigated via dsc at cooling rates from 2.5 to 20 degreesc/min, and subsequent heating at rate of 10 degreesc/min. to verify the effect of molecular weight and branching content on crystallization, three group samples were chosen: (1) linear polyethylene with low molecular weight and high molecular weight; (2) low molecular weight polyethylene with low branching content and high branching content; (3) high molecular weight polyethylene with low branching content and high branching content. the results show that crystallization temperature, crystallinity, melting temperature and crystallization rate are highly branching content-dependent. molecular weight effect is less important, compared to branching content. a dramatic decrease of crystallization temperature, crystallinity, crystallization rate and melting temperature was observed for branched samples. the non-isothermal kinetics was analyzed via the methods, developed by gupta and mo zhi-shen, and good agreement was obtained. |
