During the polyethylene (PE) blow molding process of large size drums, string-like defects, which are referred to here as worm melt fracture, can sometimes be observed on the extrudate surface. Such string-like defects, in various shapes and sizes, a

In the extrusion blow molding process of high density polyethylene (HDPE) for making of large size drums, string-like defects, which are referred to as worm melt fracture in the industry, are often observed on the extrudate surface. Such string-like

The slip behavior of several high-density polyethylenes (HDPEs) is studied as a function of molecular weight (Mw) and its distribution for broad molecular weight distribution metallocene and Ziegler–Natta catalyst resins. It is found that slip depe

The melt fracture of high-density polyethylenes (HDPEs) is studied primarily as a function of molecular weight and its distribution for broad molecular weight distribution metallocene and Ziegler–Natta catalyst resins. It is found that sharkskin an

The melt fracture instabilities of two broad molecular weight distribution (MWD) high-density polyethylenes (one Ziegler–Natta and one metallocene HDPEs) are studied as functions of the temperature and geometrical details and type of die (cylindric

The linear viscoelastic properties of two series of Ziegler–Natta and metallocene HDPEs (ZN-HDPEs and m-HDPEs, respectively) of broad molecular weight distribution (MWD) have been studied. Correlations between zero-shear viscosity and molecular wei

The influence of molecular architecture on the rapid crack propagation (RCP) resistance of a wide variety of high-density polyethylene pipes was investigated. It was concluded that high molecular weight, high crystallinity and a relatively narrow mol

Three nearly identical linear low density polyethylene resins based on copolymers of ethylene with 1-butene (B), 1-hexene (H) and 1-octene (O) were utilized to investigate the effect of short chain branch length on the mechanical properties of blown
