Synthesis and Study of Methacrylic Monomers and Polymers on the Basis of Aurones

摘要

31.1 Introduction The constant expansion of the areas of use of polymer materials, increase of requirements to their operational characteristics, and efficiency and ecological harmlessness raise the task of increasing their resistance to the action of external factors: high temperatures, oxygen, light, ozone, radiation, and others. The question of thermostability of polymers and the search for ways to increase it are always possible, because they arise at each stage of the existence of polymeric materials--in their production and storage and in the processing of products and further use. Research on the aging and stabilization of polymers, in particular, polystyrene (PS ), which is widely used in various industries, is an urgent task and has a practical focus on finding new efficient and relatively inexpensive stabilizers [1-4].
