Abstract

We report the rationallised design of aluminium initiators and their application for ROP of rac-lactide (rac-LA). Very minor change to the ligand backbone (imine reduction) to give secondary amines was found to have a dramatic effect on activity and selectivity with isotactic PLA being realised.
