Copolymerization of epoxides and CO2
The anthropogenic emission of carbon dioxide (CO2) is a major concern of global importance. However, carbon dioxide is not only a problematic waste material, it can on the other hand find use in innovative chemical processes. Given the difference in scale of the energetic and chemical use of our carbon resources (based on crude oil, it is approximately 93:7), the question arises how the chemical utilization of CO2 can be implemented into a general strategy for a global carbon balance. Thus, the question to be asked in this context is not only “How much can we reduce the CO2 emission?”, but more importantly “What can we do with CO2”?
This presentation highlights the potential impact and scientific challenges associated with the use of CO2 as building block . They will be illustrated for the production of polymers from CO2 and epoxides, the hydrogenation of CO2 to formic acid  and methanol , and the direct carboxylation of C-H bonds .
