Thermal, Mechanical and Morphological Behaviors of Binary Blends of Metallocene Polyethylene with High Density Polyethylene and Polypropylene
Rana D, Lee CH, Choe S, Cho K, Lee BH
The thermal. mechanical and morphological behaviors of two binary blends, high density polyethylene (HDPE) - metallocene polyethylene (MCPE) and polypropylene (PP) - MCPE have been investigated to compare the compatibility and molecular micro-mechanism of the blends. Both systems are thermodynamically immiscible but mechanically compatible. The그미 studies indicate that both blends exhibit two distinct melting peaks and much depression of HDPE melting peak in the blend with high MCPE content. Two discernible β transitions have been observed in the PP-MCPE blend with lower content of MCPE (up to 50%), whereas the β relaxation has been shifted to a lower temperature than that of PP-MCPE blend. The morphology of tensile fractured surface indicates that the H
