Kinetic Investigations

Cationic indium salen complexes are active catalysts for the ring opening polymerization of epoxides and other less strained cyclic ethers. Moreover, they are competent catalysts in the copolymerization of rac-lactide and epoxides to high molecular weight copolymers. Preliminary kinetic investigations with different cationic complexes revealed subtle effects of their solvent donors in the initiation rates of polymerization of epoxides.

Accelerate Development

The convergence of artificial intelligence and machine learning with material science holds significant promise to rapidly accelerate development timelines of new high-performance polymeric materials. Within this context, we report an inverse design strategy for polycarbonate and polyester discovery based on a recommendation system that proposes polymerization experiments that are likely to produce materials with targeted properties. Following recommendations of the system driven by the historical ring-opening polymerization results, we carried out experiments targeting specific ranges of monomer conversion and dispersity of the polymers obtained from cyclic lactones and carbonates. The results of the experiments were in close agreement with the recommendation targets with few false negatives or positives obtained for each class.<br>
