Abstract: The properties of vulcanized compositions based on mechanical mixtures of Ethylene propylene rubber (EPR)and Ethylene propylene terpolymer (EPTR)with PVC deteriorate compared to the properties of EPR and EPTRperoxide vulcanizers, which is explained by the poor mixing of PVC with these copolymers. In the extruder of the specified polymer mixtures -145 ° C, 36 MPa, n = 200 qra. The thermal and mechanical effects (MIC) under these conditions cause a significant improvement in the properties of the compositions based on these mixtures. The formation of EPR –PVC, and EPTR -PVX copolymers as a result of IMT in these polymer mixtures was confirmed by the construction of these copolymers with peroxide-free, PVC clusters with methemtal oxides – MgO, ZnO, and PbO (mass fraction 8-18). Modification of ethylene-propylene copolymers with PVC was carried out at a temperature higher than the flow temperature of PVC, which ensures its good dispersion in the mixture and chemical bonding with the elastomer phase, the effect of strengthening the elastic phase with the dispersed PVC phase occurs.
