Abstract
Aim of this Ph.D. project was to understand the complex and elusive molecular structure of olefin-based multiblock copolymers (OBCs), obtained via chain shuttling technology. To address the complexity of these systems, research activities were first focused on the systematic characterization of paradigmatic commercial samples. These materials were used to test different experimental and semi-empirical methods aimed at assessing the non-uniform polydisperse microstructure and the distribution of molecular mass of the blocks. In a second step, the effect of different operating parameters in the chain shuttling copolymerization on phase separation and on final properties was addressed through the synthesis of OBCs in a high-throughput regime. By closing the disambiguation loop, it was possible to determine OBCs microstructure and architecture and correlate them univocally to material structure and morphology.
