Abstract
Styrene–butadiene rubber (SBR‐1502) loaded with 50 phr carbon black (HAF) was prepared. The electrical conductivity of rubber vulcanizates was measured. It was found that milling conditions have a marked effect on the temperature dependence of the electrical conductivity σ(T) of test samples. In this case, the resistivity of prepared samples increases with remilling and has a minimum value on the σ(T) curve. Thermal‐oxidative aging of such vulcanizates decreases the conductivity of the prepared samples.Keywords
