Outline of Final Research Achievements

Development of eco-friendly materials utilizing carbon dioxide is one of the most challenging researches in modern chemistry. Polymer synthesis utilizing carbon dioxide as a monomer is an ideal system for transforming it into polymer backbone, yet the synthesis of carbon-dioxide-derived polymers having nonlinear topologies has been limited. On the other hand, progress in polymer science has produced macromolecules with various topologies, allowing us to design properties unique to them. In this study, the synthesis of carbon-dioxide-derived poly(propylene carbonate) (PPC) having either cyclic or comb-like topology has been attained. From thermal analysis, it is disclosed that cyclic PPC has higher thermal decomposition temperature than the linear analogue. Moreover, comb-like PPCs have not only deca-nano-scale ellipsoidal single molecular morphologies but also thermal degradability similar to that of linear PPCs.
