摘要：

The viscoelastic relaxation processes in polyethylene have been studied over a wide range of frequencies. Measurements were made on isotropic and oriented specimens of both low- and high-density polyethylene. Two types of relaxation process have been identified. These are a process which corresponds to shear on planes containing the c-axes of the crystallites and an interlamellar shear process which relates to the morphological structure. It is shown that the present results are consistent with those of previous investigators and that all existing data can be satisfactorily interpreted on the basis of the two proposed mechanisms. © 1969, Taylor & Francis Group, LLC.
