Abstract

Thermoplastic elastomers based on dynamically vulcanized NR/TOR/PP (rubber/PP=70/30) blends were prepared in a Haake banbury mixer. Effect of TOR content on the mechanical, dynamic mechanical and thermal stability of the rubber/plastic blends was characterized by UTM, DMTA, and TGA. On the addition of trans-polyoctylene rubber(TOR) to the rubber phase, there was a decrease in compression set and increase in tensile properties, hardness and dynamic properties as well as thermal stability or the elastomeric blends. Improvements in the properties were believed to be due to an increase in crosslink density of the rubber phase and increase in homogeneity of the blends.
