Table 1.
An overview of the polymer product ratios from the products obtained from the 5 L batch ethylene polymerization reactions: Melt Flow Index (MFI) 5 and MFI 21.6, the Melt Flow Index Ratio (MFIR), Polymer Density (PD), Powder Bulk Density (PBD), D50 Particle Size (PSE) and Particle Span after ethylene polymerization. Analysis of the produced PE materials with Gel Permeation Chromatography – Size Exclusion Chromatography – Differential Viscometry – Infrared (GPC‐SEC‐DV‐IR) provided the Mn, Mw, Mz structural parameters.
