With the introduction of DMRTs containing a sealed and pressurized sample chamber, rheological Characterization of elastomers has evolved over the last few decades into many more complex tests that provide much more molecular information about elastomers. These methods can provide a better understanding of the behavior of elastomer grades used in rubber production in a reasonable period of time.
This study used a variety of these methods on a series of elastomers with known molecular differences. The trends in the molecular nature of these elastomers and their corresponding changes in rheological data were compared.
