摘要
作者用DSC法研究了LDPE的等温和非等温结晶动力学和熔化行为。LDPE的平衡熔点和晶片折迭表面自由能分别为111.7℃和1.33×10^(-11)J/m^2,有8％的长支链参与主链结晶。
The isothermal and n on isothermal crystallization kinetics and melting behavior of low-density polyethylene (LDPE)were studied by using DSC, It is shown that the crystallization of about 8 % longer branching chain of LDPE could be observed under nonisothermal conditions. The equilibrium melting temperature and interfacial free energy per sequence as it energes from the basal plane of the nueler of LDPE were determined under isothermal conditions,
