  Preparation of nanoparticles of precisely methyl-branched polyethylene

• Image Source:

  Anisotropic nanoparticles of precise microstructure polyolefins

• Mark:

  Scheme 1

• Associated context:

  Hydrogenation of the dispersion at 60 bar H2 pressure at 65 ℃ proceeded virtually completely (Scheme 1), as concluded from the absence of olefin resonances at d 5.35 ppm in 1H-NMR spectra of isolated bulk material C15 and C19, respectively (Fig. S6 and S8, ESIw). This corresponds to a degree of hydrogenation 499.9%, which fulfills a prerequisite for meaningful studies of physical properties (vide infra).
