A Study of the Physicomechanical Properties of Plasticized Polyethylene Composites at Different Temperatures

Plasticized polyethylene composites are studied. It is established that adding dibutyl cebacinate to a polyethylene matrix provides growth of deformation characteristics of polyethylene at negative temperatures and its crack resistance due to satisfactory solubility of a plasticizer in the polymer matrix, which leads to an increase in segmental mobility of macromolecules and the formation of a homogeneous fine-spherulite supramolecular structure.
