Area of Science:

• Polymer Chemistry
• Sustainable Materials Science
• Catalysis

Background:

• Growing demand for sustainable alternatives to petrochemical-based plastics.
• Need for efficient and selective catalytic methods for renewable feedstock conversion.
• Environmental concerns driving research into biodegradable and recyclable polymers.

Purpose of the Study:

• To develop a one-pot catalytic system for producing renewable copolymers from sustainable resources.
• To demonstrate the system's capability for tandem catalysis, synthesizing poly(silylether)s followed by lactide polymerization.
• To investigate the chemical recyclability of the synthesized copolymers.

Main Methods:

• Utilized a one-pot iron-based catalytic system.
• Employed tandem catalysis for sequential polymerization reactions.
• Investigated the ring-opening polymerization of lactide.
• Performed quantitative chemical recycling analysis of the resulting copolymers.

Main Results:
