The Effect of Ammonium Modifiers on Curing Parameters and Properties of BR/Organoclay Nanocomposites Prepared by Solution Technique

The special character of rubber, being a multi component system complicates the analysis of parameters affecting cured rubber/layered silicate nanocomposites [1]. The acceleratingaction of organoclay on rubber curing has been detected for various stocks [2]. Results achieved with primary aminemodifiedclay suggested that the amine compounds react with the sulfur curatives. As the amines are pulled out from the intergallery space, the clay deintercalates [3]. In our perviouswork the effect of modifying pristine clay with benzyl dimethyl lauryl ammonium chloride and lauryl ammoniumchloride on intercalation of silicate layers in polybutadiene by solution technique was investigated and compared to nanocomposite produced using commercial Cloisite 15A nanoclay. In this study the effect of these modifiers on curing parameters and properties of cured nanocomposites will be examined.
