[a] Reactions were performed in toluene; (monomers) = 3.0; Al/Na = 0.8; tetrahydrofuran (THF)/Na = 50. [b] Conversion was determined by gravimetry. [c] Determined by size exclusion chromatography (SEC) in THF at 40 °C, calibrated with polystyrene standards. [d] Determined by DSC. [e] THF/Na = 0. N.d. = not determined.
