A possibility of modification of unsaturated rubbers with microwave radiation for increasing strength properties of elastomeric compositions based on them has been studied in the work. It has been revealed that such modification leads to improving physical and mechanical characteristics of unfilled and filled rubbers based on ethylene-propylenediene and chloroprene elastomers 1,5 – 2,5 fold on average keeping the same values of hardness. It has been established that microwave heating of chloroprene rubber provided its preliminary modification with phosphorus, boron and nitrogen containing oligomer PEDA, accelerates interaction of the modifier with the rubber. When a material exposed to super high frequency thermal treatment, the heat releases in bulk of the material, so the whole process becomes more effective. Infrared spectral characterization of initial and modified rubbers that confirmed a change in crystallinity and an increase in interaction of PEDA modifier with the rubbers has been carried out.
