I intend to characterize the viscoelastic properties during vulcanization and of the vulcanizate using a rheometer, using standard ASTM D6601. The problem is that the mixture would contain a chemical blowing agent as well, which would cause expansion somewhere during the vulcanization process. Now my guess is that this would not result in an ideal foam structure in the rheometer, since the cone-plate assembly is to be used.
Does anyone have any experience in characterizing the viscoelastic properties of elastomers using this process? I know that it can be done with a DMTA, but I was wondering if I would be able to do it for foams in the rheometer.
