[Research News] Researchers Explore New Strategies to Develop Environmentally Safe Polymer Materials

Assistant Professor Shin-nosuke Nishimura, Professor Tomoyuki Koga, and their research team have developed a simulation model to clarify how 4-position substitution in cyclic ketene acetals influences radical ring-opening polymerization.

Cyclic ketene acetals (CKAs) contain carbon atoms and oxygen arranged in a ring-like structure and are ideal for designing degradable polymers. However, the complex reaction pathways and mechanistic factors involved during the polymerization process remain unclear. In a new study from Doshisha University, researchers have developed a simulation model and conducted in-depth nuclear magnetic resonance spectroscopic analyses to determine the critical factors that can influence radical ring-opening polymerization of CKAs.
