(717e) Rheology of Novel Blends Containing Polybutylenne / Linear Low Density Polyethylene Composites

Blends of Polybutene (PB), Linear Low-Density Polyethylene (LLDPE) and Wood flour (WF) composites were developed using melt extrusion technique and maleic anhydride (MAH) as a compatibilizer. The rheological properties of neat PB, LLDPE and PB/LLDPE/WF composites with and without a compatibilizer were investigated. Mechanical properties such as tensile strength, tensile modulus, and elongation at break were measured to determine the best amount of WF percentage to be added to the composites. The addition of MAH improved the compatibility between the WF and the polymers, which contributed to the enhanced rheological properties for LLDPE. The results of tensile strength measurements indicated that 15wt.% of WF improved the tensile and flexural properties to the maximum value.
