Standard Ziegler-Natta catalysts, in contrast, are typically built from titanium and chlorine. Metallocene catalysts are homogeneous single-site systems, implying that a single catalyst is present in the solution. WebThe use of metallocene catalysts in the production of these homopolymers results in resins with improved optical and processing characteristics, combined with exceptional purity. Potential applications include fibers, medical, thermoforming, cast film, injection molding and flow modifiers in compounding. movie theatre vs theater
