Mixtures of low density polyethylene with various types of silica were investigated. The polymer matrix was crosslinked by initiation with peroxides. Four grades of silica were characterized by different methods. The presence of SiO 2 was found to lead to the formation of bound polymer, its proporti
The effect of a processing agent (Dynamar) on the viscosity and surface properties of high-density polyethylene (HDPE) has been studied. A capillary rheometer was used to measure the viscosity of HDPE compounds containing various concentrations of Dynamar as a function of time at constant apparent s
## Abstract **Summary:** The effect of melt memory on shearβinduced crystallization of a lowβdensity polyethylene melt is evaluated with a new shear DTA instrument. A critical strain is identified as the controlling factor for saturating the crystallization. Variation of this strain with the temper
