Aluminoxane catalysts and anionic initiators can polymerize 3‐butyrolactone, 3‐BL, to high molecular weight stereoregular polymers. With the racemic monomer, [R,S]‐3‐BL, anionic polymerization with alkali metal complexes can form syndiotactic polymers and aluminoxane catalysts can form either highly isotactic, syndiotactic, or atactic poly‐3‐butyrolactone, P‐3‐BL, depending on the composition and method of preparation of the aluminoxane and the conditions of polymerization.
