Carbonylative Polymerizations – A Potential Platform for Sustainable Commodity Plastics
Sustainable plastics aiming to replace the current commodity plastics should ideally have the following attributes. They are made from monomers that have low-carbon footprint and are readily available at scales and costs comparable to current commodity monomers such as ethylene and propylene. They are degradable on the surface of Earth as a fraction of them will inevitably leak into the environment. If they are made via transition metal-catalyzed polymerization, the catalyst is based on earth-abundant, inexpensive metals. And finally, they are ductile as polyethylene and polypropylene are, at least to some extent. This presentation will focus on carbonylative polymerization as a platform for making sustainable plastics. Ni catalysts with various ligands will be discussed. Incorporation of comonomers, including ethylene itself, cyclic ether, and propylene, into CO-ethylene alternating copolymer will be explored as ways to achieve the essential mechanical property of polyethylene and polypropylene replacements: ductility.
About Univ. of Akron and Its World-Renowned Polymer Research
The University of Akron has world-renowned polymer research and education since more than 110 years ago when Dr. Charles Knight had the foresight to teach the world’s first course in rubber chemistry. Today, the School of Polymer Science and Polymer Engineering has 25 faculty members, more than 150 graduate students. They are working on important and diversified research topics that are closely related to polymer chemistry, polymer physics, sustainability, advanced manufacturing, biomedicine, and energy. We have over 1500 PhD and MS alumni in 26 countries, many are in important leadership positions in academia and industry.
