Effect of Mixing Temperature on the Mechanical, Dynamic and Morphological Properties of Maleated Natural Rubber/Copolyester Blends

摘要

Maleated natural rubber/copolyester (MNR/COPE) blends with different mixing temperatures were prepared by using an internal mixer (Brabender GmbH & Co. KG, Duisburg, Germany). The effect of mixing temperatures on mechanical, dynamic and morphological properties has been investigated. It was found that the mixing temperature at 190°C provided the blend with the highest tensile strength. While the mixing temperature at 170°C showed superior elastomeric properties, in terms of tension set and tan δ with the finest morphology.
