FIELD: chemistry.
SUBSTANCE: method involves the use of briquettes from compressed, crushed plant material of 1.5" or less, containing bagasse, rubber, residual water and not more than 5 wt % of the leaves. The density of briquettes is 40-325% higher than the density of unpressed vegetable material. A purified, hard rubber is obtained which contains 0.05-0.5 wt % of impurities, 0.2-1.5 wt % of ash and 0.1-4.0 wt % of the resin if it is dried to such a state that it contains 0.8 wt % of volatile substances.
EFFECT: method makes it possible to improve the isolation of rubber from a plant that is not hevea.
