Abstract: The physical properties of polymer materials are greatly affected by the primary structure of the polymer chains that make up the material. Therefore, the development of a synthetic method for controlling the primary structure and the development of an analytical technique to elucidate the structure are important issues.
In this study, novel synthetic methods for the polymerization of controlled and highly branched PMMAs and the polymerization of acrylamides with dual control of molecular weight and stereoselectivity were developed. For the first time, trapped ion mobility mass spectrometry was used to determine both the effect of the branching structure on the molecular volume of highly branched PMMA and the effect of tacticity on the polymer structure of PDEAA in the gas phase.
