• Evidences of Long‐Chain Branching in Ziegler‐Natta Polyethylene Homopolymers as Studied via SEC‐MALS and Rheology

  Summary Comprehensive polymer architectural studies were carried out on a group of Ziegler‐Natta (Z‐N) polyethylene homopolymers via size‐exclusion chromatography coupled with multi‐angle light scattering (SEC‐MALS) and rheology. Although Z‐N resins are traditionally viewed as linear polymers, more

• Liquid Chromatography of Synthetic Polymers under Critical Conditions of Enthalpic Interactions 4. Sample recovery

  Reduced sample recovery is a frequent feature of liquid chromatography of macromolecules under critical conditions of enthalpic interactions, LC CC. Several methods of assessment of LC CC sample recovery are compared. A novel approach is based on an online combination of the LC CC column with a no more

• Ultra‐high‐performance size‐exclusion chromatography of synthetic polymers. 1. Demonstration of capability

  Ultra‐high‐performance size‐exclusion chromatography (UHP SEC) is a newly developed disruptive technology that allows the high‐resolution separation of synthetic polymers in as little as two minutes. The capability of UHP SEC for the characterization of synthetic polymers in both organic solvents more
