| Abstract: | 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, |
