摘　　要：The dispersion of functional nanometer materials in polyolefin/clay nanocomposites is a key factor to determine the performances of mate-rials[1].In this research,the sepiolite with high specific surface area and good adsorption was introduced into the molybdenum-based butadiene polymerization system.Sepiolite-supporting MoCl5(Mo)function as the main catalysts,together with the alkyl aluminum(Al)substituted by m-cresol to form the butadiene coordination polymerization catalyst system to prepare high vinyl polybutadiene(HVPB)/sepiolite(Sep)nanocomposite.
