Popis:	The properties of ultralow-density polyethylenes (ULDPE) have been studied using temperature rising elution fractionation (TREF) as both an analytical and preparative process. TREF was employed to determine the short chain branch distribution and to fractionate the polymer into fractions that enabled further properties studies, including carbon-13 nuclear magnetic resonance, differential scanning calorimetry, dynamic mechanical thermal analysis, density gradient studies, gel permeation chromatography, analytical TREF, and some simple tensile tests. The results of these studies are reported here.
