Abstract:
1. An elastomeric blend comprising an elastomeric composition and carbon black, the above elastomeric composition consisting of: (i) one or more elastomers (A) selected from ethylene-propylene (EPM) copolymers and ethylene-propylene-diene (EPDM) terpolymers; (ii) one or more elastomers (B) selected from ethylene-propylene (EPM) copolymers and ethylene-propylene-diene (EPDM) terpolymers and relative mixtures, the above one or more elastomers (B) having been previously treated with at least one hydroperoxide at a process temperature ranging from 100° C. to 250° C., with the proviso that said hydroperoxide has a halving time, at the process temperature, not lower than 5 times the process time: the weight ratio between the elastomers (i) and (ii), having a sum of 100, being from 0/100% to 90/10.
