摘要：
The authors have studied the special features of the process of structuring the LDPE on prolonged annealing in the stressed state at a temperature below T//m by the methods of wide annealing a fine structure appears in the small angle diffraction patterns - three maxima. The wide region of heat absorption in the melting thermograms breaks down into three maxima, only one of them corresponding to the melting of the crystalline phase the characteristics of which during annealing remain practically unchanged. The set of structural and thermophysical characteristics shows that the most fundamental changes as a result of annealing occur in the amorphous phase.
