Abstract
Methods for activating the surface of rubber crumbs using different physicochemical effects are examined. The properties of industry-produced activated rubber crumbs and the prospects of their use in different polymer compounds are analysed. The influence of the degree and depth of devulcanisation of the surface layer of rubber crumbs on the rheological and physicomechanical properties of rubber composites is shown. Promising directions of modern research in the area of surface activation of rubber crumbs are described. It is shown that the application of microwave energy to activate rubber crumbs directly before the manufacture of articles from them makes it possible to obtain products with improved properties.
