Abstract
Anionic polymerization of 2-vinylpyridine shows significant solvent ef fects on the polymer stereochemistry. Polymerization with butyllithium in tetrahydrofuran (THF) yields a largely isotactic polymer, while po lymerization with butyllithium in tetramethyl-ethylenediamine (TMEDA) results in a material with nearly the same stereochemistry as radical polymerization. Semiempirical molecular orbital calculations were used to explain these solvent effects.
