Inquiring into Structure of Hyperbranched Polyethylene Produced in Radical Polymerization Process

Abstract

This paper presents the analysis of rubberlike hyperbranched polyethylene (PE) deposits in separators and high-pressure (HP) recycle system with use of NMR spectroscopy 13С, X-ray phase analysis and differential scanning calorimetry; polymer extraction separation with boiling o-xylene and comparison of fraction characteristics have been carried out. With literature data and process conditions taken into account the potential reason of such structure polymer synthesis is being under discussion.
