Key Points

To develop a sustainable catalytic method for synthesizing isosorbide-based polycarbonates with controllable molecular weight using carbon dioxide-derived precursors and metal-free ionic liquids.
Utilized the carbon dioxide-derived building block dimethyl carbonate (DMC) as a monomer alongside bio-based isosorbide (ISB).
Applied task-specific ionic liquid catalysts designed with regulated hydrogen-bond donor and acceptor capabilities to promote polymerization without metal additives.
Achieved successful synthesis of isosorbide-based polycarbonates with adjustable molecular weights by modulating the hydrogen-bonding characteristics of ionic liquid catalysts.
Demonstrated an effective and metal-free synthetic route for polycarbonate production utilizing sustainable, carbon-dioxide-based feedstocks.

Implication

Experimental synthesis reveals tunable molecular weight for isosorbide-derived polycarbonates using ionic liquid catalysts, suggesting a sustainable pathway for bio-based plastics.

Abstract

A sustainable strategy for synthesizing ISB-based polycarbonate (PIC) with adjustable molecular weight has been developed, utilizing the CO 2 -based compound dimethyl carbonate (DMC) as a monomer and ionic liquids (ILs) as metal-free catalysts.
