Abstract:
The main approaches to stabilization of polymers and requirements to anti-ageing agents are discussed. Considerable attention is paid to the progress in the studies of the stabilizing activity of various substances in polyolefin- and polyvinyl chloride-based compositions. Particular demand for environmentally benign organic heat stabilizers and antioxidants is noted. The so-called mesogenic structures serving as effective light and heat stabilizers for polymer composites are presented. The effects of mesogens on the supramolecular structure of polyethylene, deformation and relaxation properties and thermal parameters as well as melt flow index, tribological properties and other properties of polymer materials are discussed.
