Polymerization process for producing polyolefin elastomer, cation-generating cocatalyst for activating a metallocene procatalyst, polyolefin elastomer possessing a unique combination of properties and products manufactured therefrom

By using a special type of metallocene catalysts for polymerization of polyolefin elastomers are a unique combination of performance, that is, high molecular weight (Mw), Gao Menni viscosity (ML1+4 under 125 ° c), low dispersion index (Mw/Mn), low glass transition temperature (Tg) and low hysteresis (Tan δ). The polyolefin elastomers for the manufacture of a variety of products, including rubber products, such as hoses, belts and molded products, containing one or more other hydrocarbon polymers, polymer blends, and elastomers described therein as a viscosity regulator Lube. Publicly used before activation of metallocene catalysts cationic catalysts, selection in the alkene monomers in presence of activation.
