The direct synthesis of poly(styrene-b-ethlene) and its chain-end carboxylation have been investigated by a combination of size exclusion chromatographyu (SEC) and ¹H NMR spectroscopic analysis. The block copolymer and the chain-end carboxylated block copolymer are obtained from the sequential ethylene monomer addition to poly(styryl)lithium at 50℃ in cyclohexane and the direct reaction on poly(styrene-b-ethyenyl) lithium including TMEDA with CO₂ gas, respectively. The molecular weight of the polyethylene block is low due to the insolubility in hydrocarbon solvent.
