✦ Synopsis

Abstract

The current study provides indications for improving the properties of dissimilar rubber blends. As solubility is a key factor for the distribution and a driving force for the migration of curatives in dissimilar rubber blends, it is of importance to have precise data of their solubilities. The solubilities of (insoluble) sulfur and the accelerators CBS, MBT and DCBS are measured at RT and at 60 °C, in lightly crosslinked SBR, NBR and EPDM. The experimental results correlate well with calculated solubility parameters, as determined using the method of Hoftijzer and van Krevelen.

## Abstract Using previously obtained data on the solubilities of curatives in SBR, EPDM and in NBR, different mixing procedures were performed on 50/50 SBR/EPDM and NBR/EPDM blends. In contrast to a previous phase‐mixing study, the curatives were added to separate phases before final blending, in
