| Notes | Solution polymerized styrene-butadiene rubber（SSBR） was synthesized by batch anionic copolymerization,using cyclohexane/hexane as solvent,n-BuLi as initiator,ethyl tetrahydrofurfuryl ether（ETE） as modifier,butadiene and styrene as monomer,the effects of initiation temperature and ETE dosage on monomer conversion and vinyl content of SSBR were investigated,and the effect of coupling agent kind on properties of SSBR and the optimum coupling conditions were studied.The results showed that the number-average molecular weight of the oil extending star-shaped SSBR was about 29.00 × 104 and the mass fraction of vinyl was above 60％,and the mechanical and dynamic mechanical properties of synthesized SSBR were better in the presence of ETE modifier and CH3SiCl3 coupling agent at initiation temperature 35-45 ℃,mass fraction of ETE 350 × 10-6,environmental friendly extending oil VIVATEC 500 37.5 phr.With increasing coupling temperature and time,the coupling efficiency increased and reached above 50％ at 55 ℃ for 15 min. so |
