摘要: Early and late transition metal single-site catalysts revolutionised the polyolefin manufacturing industry research with their ability to make polymers uniform microstructural properties. Several of these are currently used commercially produce commodity differentiated-commodity resins. The key rapid success industrial implementation resided in fact that they could be without major modifications polymerisation reactors previously heterogeneous Ziegler–Natta Phillips catalysts. Since most processes use slurry or gas-phase reactors, soluble must supported on adequate carriers ensure not only high activity, but also formation polymer particles proper morphology bulk densities. In this article, we will review several methods for supporting early a variety supports. © 2011 Canadian Society Chemical Engineering
