Effect ofcarbon blackon chain mobility and structure of
Dynamic mechanical properties of polyisobutylene, butyl rubbers, Paracril, cis‐1,4‐polybutadiene, reinforced with EPCblack, were determined in the temperature range −150‐+170°C., in thefrequencyrange 2–20 kcycles/ the amorphous polymers, reinforcement causes an increase of sound velocity at any temperature, while the glass transition point T g and the thermal coefficient of ...
