| Abstract: |
| The effect of bio-based liquid isoprene rubber （LIR）-50 on the properties of emulsion
polymerized styrene butadiene rubber（ESBR） compound was studied. The results showed that compared
with environmental friendly aromatic oil，LIR-50 could better improve the processability of the compound.
LIR participated in the crosslinking reaction of the compound，which could better maintain the physical
properties of the compound. Adding an appropriate amount of LIR-50 could reduce the Payne effect of the
compound，improve the dispersion of carbon black，and significantly improve the wet skid resistance while
maintaining its low rolling resistance and low heat build-up. |
