Abstract

One major remaining challenge in development degradable polymer materials is designing efficient catalytic systems for the controllable synthesis of high molecular weight polyesters. In this study

we reported the novel asymmetric Al complexes with a Salen bond and a Catam bond in the ligand framework. The specific ligand structure played an important role in the activation of the central metal atom to the cyclic ester monomers (

e.g.

-caprolactone (

-CL)

and

-valerolactone (

-VL)). The Al complexes exhibited excellent activity for the cyclic ester polymerizations

generating high molecular weight polyesters. Initially

the effects of aluminum complex structures and polymerization conditions (reaction temperatures

monomer ratios

and monomer structures) on catalytic polymerization were investigated systematically. After optimizing the reaction conditions

the asymmetric Al complex with a benzyl alkoxy as axial group

could controllably polymerize

-CL

-VL

and their mixed monomers

to polyesters with high number-average molecular weight (175.7-443.8 kg·mol

-1

) within 10 min. Furthermore

the relationship between chain structures (n

umber-average sequence lengths of PCL and PVL) and reaction conditions (reaction temperatures and monomer ratios) was analyzed. And the thermal properties of random polyesters were characterized in detail.
