Abstract

Abstract : A highly active trinuclear salen–Al complex was applied in the cocatalyst-free copolymerization of epoxides and anhydrides via intramolecular interaction. Abstract : A rare example of a trinuclear salen–Al complex is reported. Due to the intramolecular interaction, the trinuclear salen–Al complex can catalyze copolymerization with high activity in the absence of any cocatalyst. On the basis of a covalent coordination insertion mechanism, ABC(1)C(2) type tetrablock copolymers were produced using an hydroxyl initiator.
