【Abstract】 With polyisoprene dilithium as an initiator, cyclohexane as a solvent ,tetrahydrofuran as a polar additive, isoprene styrene butadiene as monomer, a new thermoplastic elastomer S(IB)S was synthesized by two steps. The characterization of the product was carried out by IR, 1H-NMR, TEM and DSC, and its physic-mechanical properties were also examined.更多还原
