- Аннотация: Mixtures of low-density polyethylene (Tm = 108°C; enthalpy of melting, 80 J g−1) with various low-molecular-weight organic components have been subjected to plastic deformation under a pressure of 1 GPa on an anvil-type high-pressure device. Melamine, cyanuric acid, adamantane, tetracene, fumaric acid, succinic acid, aspartic acid, indigo, anthracene, methyl orange, congo red, and safranin have been used as a low-molecular-weight component. The deformed mixtures have been studied using the DSC method. The thermograms of the mixtures at temperatures below the polymer Tm exhibited both endothermic and exothermic peaks. The endotherms and exotherms have been associated with the melting of small polymer crystallites and the crystallization or recrystallization processes in the polymer phase, respectively. In some mixtures, thermal effects were detected at temperatures above the polymer Tm, 117–161°C. These effects have been attributed to electrostatic interaction at the polymer/low-molecular-weight component interfaces.
