Influence on compounding methods on rheology and morphology of linear low density polyethylene/poly(lactic acid)
Appl. Rheol. 26:6 (2016) 64746 (8 pages)

Linear low density polyethylene (LLDPE)/poly lactic acid (PLA) blends were prepared via different melt mixing methods. The
effects of various blend compositions and two mixing methods on morphological and rheological behavior of the blends were
studied. Scanning electron microscope (SEM) was used to investigate morphology behavior of the blends. The rheological studies
illustrated that all samples presented shear thinning behavior and the PLA-rich blends exhibited a Newtonian region. It
was found from the rheological measurements that the LLDPE/PLA (75/25 w/w) prepared by batch mixer exhibited higher
values of storage modulus and complex viscosity, which is in agreement with the morphology results. In addition, using the
different mixing methods, significant differences in the morphological results for the LLDPE/PLA (50/50 w/w) blend were
observed. Finally, the results showed that the blends prepared by batch mixer exhibited better morphology, higher storage
modulus, and complex viscosity.
