  text: For the first time, poly(N-isopropylacrylamide) (PNIPAAm) star polymers with
    a β-cyclodextrin core are characterized in detail by size-exclusion chromatography
    (SEC) with triple detection to experimentally verify the number of arms. A combination
    of a refractive index detector, multi-angle laser light scattering detector, and
    an online-viscosimeter was used for branching analysis. At first, the SEC system
    was calibrated and the detector setup was validated using linear polystyrene reference
    polymers. The applicability of the established triple detection SEC for branching
    analysis was shown by the analysis of two commercially available polystyrene star
    polymers. Due to the high molar masses of the star polymers, both the contraction
    ratio g and g′ could be determined independently, thus allowing the calculation
    of the viscosity shielding ratio ε. Finally, the branching analysis of the PNIPAAm
    star polymers could experimentally confirm the assumed arm number of up to 21
    arms. Moreover, an increasingly compact molecular structure and the influence
    of the arm number on the viscosity shielding ratio could be shown.
