FUNCTIONALIZED OLIGOMERS AND POLYMERS AS STABILIZERS FOR CONVENTIONAL POLYMERS

The low physical persistence limits the exploitation of the inherent chemical efficiency of stabilizers in polymers used under demanding conditions in domestic, engineering or medical applications. The problem can be solved by means of stabilizers having an increased molecular weight and a proper molecular architecture. Methods of synthesis, examples of structures and data dealing with properties and activity mechanisms of polymeric stabilizers are summarized with the aim of exploiting in an optimum way the knowledge of the chemistry of polymeric stabilizers for practical stabilization, to attract to a greater extent physical and physicochemical attention to solve involved open problems, and to increase by this approach the complex understanding for a more proper exploitation of physically persistent additive systems.
