Abstract

The influence of the chemical nature of macromolecules formed after the plasticization of isoprene rubber (SKI-3) on the stickiness of rubber mixtures based on its plastics has been studied. During plasticization, alkyl-, allyl-, oxygen-containing macroradicals are formed and their recombination occurs in different combinations. The greatest increase in stickiness occurs when alkyl- and allyl- macroradicals predominate in the rubber mixture. A less pronounced effect is observed with the predominance of oxygen-containing macroradicals. Recombination of the resulting macroradicals leads to a decrease in stickiness.
