摘要: Rheological characteristics and morphology of low-density polyethylene (LDPE) /ethylene vinyl acetate copolymer (EVA) high-density (HDPE)/EVA blends were compared. Morphological examinations clearly reveal a two-phase in which the LDPE/EVA have smaller dispersed domain size than HDPE/EVA Furthermore, shows finely interconnected at 50wt% EVA while exhibits coarse co-continuous same composition. The morphological observations can be attributed to lower viscosity ratio interfacial tension system. Palierne model also successfully fits experimental data giving higher values for system as compared LDPE/EVA.
