Abstract

Abstract: The extensional rheology properties of low-density polyethylene (PE-LD), linear low density polyethylene (PE-LLD), and high-density polyethylene (PE-HD) were studied in melt spinning process. It showed that both melt strength and extensional viscosity of PE-LD, PE-LLD, and PE-HD melt decreased with increasing temperature. With increasing extensional strain rate, both extensional stress and extensional viscosity of PE-LD, PE-LLD, and PE-HD melt decreased.

Key words: low-density polyethylenelow-density polyethylene, linear low density polyethylene, high-density polyethylene, melt spinning, extensional rheology behavior
