Hasegawa H., Nagata Y., Terao K., et al. Synthesis and solution properties of a rigid helical star polymer: Three-Arm Star Poly(quinoxaline-2,3-diyl). Macromolecules, 50(19), 7491-7497, September 28, 2017. Copyright © 2017, American Chemical Society. https://doi.org/10.1021/acs.macromol.7b01797.

Six semiflexible helical three-arm star poly[5,8-dimethyl-6,7-bis(propoxymethyl)quinoxaline-2,3-diyl] (A3PQ) samples which have different arm lengths ranging in the weight-average molar mass Mw from 1.5 × 104 to 2.5 × 105 g mol-1 were synthesized via the living polymerization of the corresponding 1,2-diisocyanobenzene using a trifunctional palladium initiator. The particle scattering function P(q), the z-average mean-square radius of gyration S2z, and the intrinsic viscosity [ν] for the A3PQ samples were determined from light and small-angle X-ray scattering and viscosity measurements in tetrahydrofuran at 25 °C. The obtained data were compared with modern theories for the wormlike star. The experimental P(q) data were represented by the wormlike star model connected with a universal joint. The other data were comparably explained by the same model.
