This work reports the preparation of a hydroxyl terminated polystyrene-<i>b</i>-polybutadiene-<i>b</i>-polystyrene triblock copolymer (SBS) with high cis-1, 4 content via a novel nickel catalyst, [η³-Ni(CH₂CHCHCH₂OOCH₃)][BPh<sup>F</sup>₄]. FT-IR, ¹H-NMR, and <sup>13</sup>C NMR indicated that the polybutadiene segment of the copolymer contains greater than 90% cis-1, 4 structure, indicating achievement of the objective. Toward the functionalization goal, a hydroxyl group was successfully introduc ...[more]
