Polymerization of hex-1-ene by homogeneous zirconocene and hafnocene catalysts in compressed solution
Abstract
Poly(hexene) with very high molecular weight is produced at 250 MPa (2500 atm) with (C5HMe4)2HfCl2–methyl aluminoxane (MAO) as catalyst; the dependence of the polymerization on the reaction pressure (0.1 MPa–1.5 GPa) and the substituent pattern of a zirconocene catalyst is described.
