METHOD OF PRODUCING COMPOSITION FOR OIL-BENZENE-RESISTANT PLASTIC Russian patent published in 2017 - IPC C08L27/06 

FIELD: chemistry.

SUBSTANCE: mixing of polyvinyl chloride, dioctylphthalate, calcium stearate, tribasic lead sulfate, epoxy resin is carried out. Mixing of the mixture components is carried out under normal conditions, the composition is prepared by swelling the resulting mixture for 5 hours at 80°C and its mixing with NBB-33 butadiene-nitrile rubber. The plasticate is produced by extruding and granulating the resulting composition.

EFFECT: increase the oil and petrol resistance of the plastic material while maintaining its strength characteristics and thermal stability.
