| Abstract: |
| The application of molybdenum-catalyzed high vinyl polybutadiene rubber（HVBR） in the tread compound of PCR tire was investigated.The results showed that，compared with solution polymerized styrene butadiene rubber（SSBR） compound，SSBR/natural rubber blend and SSBR/butadiene rubber blend，SSBR/HVBR（20 phr） blend had the best dynamic mechanical properties with high wet skid resistance and low rolling resistance. |
