<p>In a method of reclaiming rubber waste by which the rubber is first crushed and then devulcanized the rubber crumbs are mixed with a polymeric softener elected from the group of liquid polybutadienes with addition 1,2 - 1,4 having a molecular weight ranging from 250 to 10000 and such a mixture comprising 4 to 20% by weight of a softener and 95 to 80% by weight of rubber crumbs is exposed to a compressive, shear and heat stress at a temperature ranging from 190 to 280 °C. Before the exposing the mixture to the compressive and shear stress the mixture is allowed to swallow for 24 to 80 hours at a temperature 15 to 200 °C.</p> |
