Abstract

Abstract: In this work, cross‐linking at low temperature (90°C) of butadiene rubber (BR) using a vulcanizing system based on a hydroperoxide and ionic liquids (ILs) has been evaluated. Composites of BR with cumene hydroperoxide (CHP) and selected ILs have been prepared and tested. In order to elucidate the influence of novel systems on the cross‐linking as well as on the properties of the final product, BR composites have been characterized by different techniques, that is, rheometrical properties, cross‐linking density determination, as well as mechanical strength and weather aging resistance studies. Herein, the influence of weather aging on the properties of the samples is performed and further discussed. CHP and ILs were found to be an effective peroxide system, which enabled to decrease the energy consumption during vulcanization as well as the amount of applied CHP. Taking into account cross‐linking efficiency, system containing 1, 3‐dimethylimidazolium methyl sulfate (IS), or tetrahexylammonium tetrafluoroborate (AB) seems to be the most active.
