Abstract
The synthesis of a model ABA type triblock copolymer, consisting of syndiotactic polystyrene (SPS) (A) and polyisoprene (PIP) (B) blocks is demonstrated. The 3,4‐vinyl carbon on the polyisoprene side chain in the SPS‐graft‐PIP was effectively lithiated with sec‐butyllithium, which was subsequently utilized for further living anionic polymerization of isoprene. Propagating polyisoprenyl anions were terminated with 1,3‐diiodopropane to make the ABA type triblock copolymer. From the 1H NMR and GPC measurements, the composition ratio of ABA block was found to be almost 1:3:1.
