The present article proposes a simple way to dramatically alter the pore architecture of Mg(OEt) 2 ‐based Ziegler–Natta catalysts by the addition of a small amount of i ‐propanol during the synthesis of Mg(OEt) 2 . The incorporated i ‐propoxide distorts the crystalline structure of Mg(OEt) 2 , finally causing the phase transformation and significant densification of particles. Such modifications completely alternate the pore architecture of resultant catalysts, which contribute to the design of catalytic properties.
