简介 FIELD : chemistry. SUBSTANCE : invention relates to nanostructured polymers, production and use thereof. The conjugated diene-based nanostructured polymers are obtained in the presence of catalysts which are based on compounds of rare-earth metals, followed by reaction with a nano-linking agent. The obtained polymers have bimodal molecular weight distribution. The high-molecular weight component has average molecular weight higher than 2000000 g/mol and is in amount of 1-20 wt % with respect to the polymer. Content of gel in the polymer is less than 1% and content of 1, 2-vinyl links with respect to the polymer ranges from 0.3 wt % to 1 wt %. EFFECT : disclosed polymers have good processing properties, rubber mixtures based on said polymers have an improved set of properties and higher tear resistance. 5 cl, 3 dwg, 3 tbl, 10 ex
