“…The degree of crystallinity of MOP-CL Þ lms, obtained from both MOPCo-BL and MOPLm-BL Þ lms, were calculated from ∆H values against the standard ∆H value of hypothetical 100% crystalline polyethylene (33) . The calculated crystallinity values (36% for MOP-CL Þ lm obtained from MOPCo-BL and 39% for MOP-CL Þ lm obtained from MOPLm-BL) agree well with the range of crystallinity (~35%) for branched polyethylene (34)(35)(36) . Solubility behavior (Table 2) as well as the FTIR spectrum (Table 3) of MOP-CL Þ lm supports in favor of polyethylene as the carrier layer polymer.…”

Recycled polyethylene containing very small amounts of nylon-6 or PET, which is the source of flexible oil pouches, may find applications as raw materials for other polymer products after the recycled polymer is properly identified and characterized before reprocessing. Proper identification and characterization of the polymer components present in the waste has considerable importance for obtaining value-added products. In this investigation, post-use oil pouch films, collected from municipal garbage, were first subjected to sorting, washing and drying. Then the dried films were fractionated by dissolving in solvents. The isolated component polymers were characterized and identified by solvent fractionation, FTIR, DSC-TGA and WAXD analysis.

The effects of ultrasonic oscillations on linear viscoelastic behaviors of metallocene‐catalyzed linear low density polyethylene (mLLDPE) and its blends with low density polyethylene (LDPE) were investigated in this article. The experimental results showed that ultrasonic oscillations can increase the cross modulus, characteristic time, plateau modulus, complex viscosity, zero shear viscosity, and flow activation energy of mLLDPE. Molecular weight of mLLDPE increases but molecular polydispersity index decreases in the presence of ultrasonic oscillations. It has been found for mLLDPE/LDPE blends that the addition of LDPE as well as ultrasonic oscillations can decrease the cross modulus but increase the characteristic time of the blends. The complex viscosity, zero shear viscosity, and flow activation energy of the blends increase by the addition of LDPE, but decrease in the presence of ultrasonic oscillations. Shear thinning effect of the blends is improved because of the addition of LDPE. © 2005 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 43: 3030–3043, 2005

ABSTRACT:The influences of ultrasonic oscillations on rheological behavior and mechanical properties of metallocene-catalyzed linear low-density polyethylene (mLLDPE)/ low-density polyethylene (LDPE) blends were investigated. The experimental results showed that the presence of ultrasonic oscillations can increase the extrusion productivity of mLLDPE/LDPE blends and decrease their die pressure and melt viscosity during extrusion. Incorporation of LDPE increases the critical shear rate for sharkskin formation of extrudate, crystallinity, and mechanical properties of mLLDPE. The processing behavior and mechanical properties of mLLDPE/LDPE blends were further improved in the presence of ultrasonic oscillations during extrusion.
