Unformatted text preview: q / T p 2 ) versus E a/ RT p should be linear and the apparent activation energy can be obtained from the slope of the straight line. 1.5 Dynamic Vulcanization and Thermo Haake Rheometer As mentioned above, elastomer/thermoplastic blends have become technologically and commercially viable as thermoplastic elastomers in recent years. They have many properties of elastomers, yet they are processable like thermoplastic. They do not need to be vulcanized during fabrication into end-use parts. Thus, they offer a substantial economics, design, and processing advantage regarding the fabrication of the finished parts. For many end uses, the ideal elastomer/plastic blend comprises finely divided -ln(q/ T p 2 ) =E a / RT p-ln(AR/E a )...
