    Abstract

    Abstract Image

    Chain-walking (CW) catalysis applied to α-olefin polymerization gives rise to structurally unparalleled macromolecules with diverse topological and rheological properties. The specific motion pattern of the CW catalyst along the polymer chain is easily manipulated by varying synthesis parameters such as monomer concentration, temperature, and time or by adjusting the steric and electronic effects of the catalyst’s ligands or choice of central metal. While their structural potential has been extensively studied, the experimental identification has often been single-sided. Modern techniques in liquid chromatography provide a suitable approach to investigate the complex dimensions of CW polyethylene (PE). In this study, advanced interaction chromatography in temperature and solvent gradient modes as well as comprehensive two-dimensional chromatography (2D-LC), coupling of interaction (IC), and size exclusion chromatography (SEC) are combined with multidetector high-temperature SEC (HT-SEC) to characterize the multidimensional heterogeneity of CWPE. Nuclear magnetic resonance and Fourier transform infrared spectroscopy provide quantitative information about the types and numbers of branches. The complementary characterization techniques give insight into highly diverse branching topologies within narrow molar mass distributions of the CW polyethylene.
