Life of the modern person cannot be presented without poly-mers and products from them. With each year the assortment of again synthesized high-molecular connections is increased. But they for practical purposes should be stabilized from various kinds’ destruction more often. Studying of processes of ageing and stabilization of polymers is one of the most important directions of a modern chemical science. Therefore works of complex research on creation of new stabilizers and modifiers have the big theoretical and practical value. Works offered to the reader are a part of results of authors on extensive research in specified areas of polymeric chemistry.
