A series of poly(propylenes) (PPs) were prepared by slurry polymerization using a MgCl2-supported transition metal catalyst. Two different external donors (EDs) were used: diphenyl dimethoxysilane (DPDMS) and methylphenyl ...
For the first time polyolefms are separated according to tacticity by liquid chromatography. High-temperature gradient HPLC is shown to be suitable for the separation of polyethylene and polypropylene. As the stationary ...
