摘要：
Blends of Polyethylene terephtalate (PET) and Linear Low Density Polyethylene (LLDPE) compatibilized with maleic anhydride-grafled-LLDPE (MAH-g-LLDPE) were characterized. The addition of MAH-g-LLDPE produced a fine dispersed phase morphology and improved processability of blends. A decrease on the crystallization temperature and on the degree of crystallinity of the polyester and an increase on the elastic modulus and on the stress at break were observed. These effects could be attributed to the reduced interfacial tension as a result of the promoted interaction between the polymers by the functionalized polymer.
