The Dow Chemical Company is the world’s largest producer of Linear Low Density Polyethylene (LLDPE). The Dowlex<sup>TM</sup> family of polymers, produced from heterogeneous Ziegler-Natta catalysts, provide unique molecular weight and short-chain branching distributions which yield a balance of performance properties. Recent efforts have explored the extent to which these polymer distributions can be tuned as a function of the physical properties of the underlying MgCl2 support. To this end, crystalline MgCl2 supports have shown a propensity to improve the homogeneity of the resulting polymer distribution, both in terms of molecular weight and short-chain branching. This talk will highlight considerations used in rational synthesis of supports for heterogeneous catalysts, as well as practical limitations of such approach.
