Abstract
A commercial, linear, low-density polyethylene (LLDPE) synthesized by a metallocene catalyst was analyzed by temperature-rising elution fractionation, Fourier transform infrared, and 13C-nuclear magnetic resonance spectroscopy. It was found that the LLDPE sample is mainly butyl branch. The degree of branching decreased with increasing elution temperature. The results from wide-angle x-ray diffraction and size exclusion chromatography confirmed that the fractionation was based on the ability of fractions to crystallize rather than molecular weight. The LLDPE sample has a narrow molecular-weight distribution.
