Abstract

Tensile properties and thermal characteristics of blends made from linear low-density polyethylene and polyvinyl alcohol have been investigated. 3-propyl methacrylate was used as a coupling agent. The blends were melted and mixed using a Haake Rheomix at 150 °C and 50 rpm for 10 min. Results show that the incorporation of Si A174 resulted in the increase of the tensile strength and Young’s modulus but decrease in the elongation at break of the LLDPE/PVA blends. The crosslinked formation between LLDPE, PVA, and Si A174 was confirmed by decrease of melting temperature and degree of crystallinity as demonstrated by differential scanning calorimetry study.
