Expert Talk on “Synthesis and applications of polymers based on CO2 and CS2”

19 Aug 2021


An Expert Talk on “Synthesis and applications of polymers based on CO2 and CS2” was organized by the Department of Chemistry, Manav Rachna University on 19th August, 2021. Professor Bungo OCHIAI, Ph.D., Department of Applied Chemistry, Chemical Engineering, and Biochemical Engineering, Graduate School of Science and Engineering, Yamagata University Yamagata, JAPAN delivered the talk which was attended by students of M.Sc. and B.Sc. (Hons) Ph. D Scholars and faculty members from the various universities.

Dr. S. K. Shukla, HOD Chemistry, and Dr. Jaya Tuteja, Assistant Professor Chemistry, welcomed the guest and the audience. Dr. S. K. Shukla introduced the guest speaker and talked about the application of Quantum in various fields. More than 70 participants joined the session.

Professor Bungo OCHIAI, Yamagata University, Yamagata Japan has over 25 years of experience in the field of polymer synthesis. Currently working as Vice-Dean (education), Faculty of Engineering, Yamagata University. He completed his Doctor of Engineering in March 2001 from Interdisciplinary Graduate School of Science and Engineering, Tokyo Institute of Technology, Japan. He is an active member of the Chemical Society of Japan, Society of Polymer Science Japan, American Chemical Society etc. Professor Bungo OCHIAI More than 127 research papers published in peer reviewed Journals and conferences, Wrote Book Chapters Polymer Chemistry.

He initiated his talk by the Synthesis and applications of polymers based on CO2 and CS2 which is intended to serve as a reference for Postgraduate, graduate level students as well as researchers from all fields of science. He discussed how transforming CO2 into organic materials in low energy is a desirable method utilizing the abundant resource to save using petroleum resources. The reaction of CO2 and epoxides giving five-membered cyclic carbonates is a good candidate owing to its relatively mild conditions. This reaction has been used for syntheses of various polymers, but multiple steps were required.


Lecture covered the elementary steps involved in the combined system comprising carbon dioxide fixation and radical polymerization through radical polymerization of glycidyl methacrylate (GMA) under a carbon dioxide atmosphere at 1 atm. The resulting polymers are homopolymers or copolymers of GMA and 1,3- dioxolan-2-one-4-ylmethyl methacrylate (DOMA), whose ratios can be controlled by the reaction conditions. The obtained polymers are potentially applicable to paints, adhesives, optical materials, and polymeric supports for lithium ion batteries. The lecture was very informative and beneficial to the students as well as faculty. The session ended with a note of thanks by Dr. Arpit Sand, Associate Professor Chemistry Department.
