What is Determination of Some Kinetic Constants in Ethylene Polymerization about?
We have obtained ultra-high molecular weight polyethylene by using a MgCl 2 / Ti(OBu) 4 /SiCl 4 /PMS/TiCl 4 -based catalysts. We derived an equation that could calculate some kinetic constants, investigating the deactivation reaction mechanism in the polymerization process. The results indicate that the reaction proceeded with a bimolecular deactivation reaction mechanism for initial 20 min, and then monomolecular deactivation reaction mechanism. Knowing the molecular weight distribution values, we derived an equation that can calculate the concentration of active centers and some velocity constants and the average lifetime of the growth chain that are difficult to determine from the relationship between water average polymerization and time. Using MgCl 2 /Ti (OBu) 4 /SiCl 4 /PMS/TiCl 4 based catalysts, the deactivation reaction mechanism was changed with time, indicating that the reaction proceeded with a bimolecular deactivation reaction mechanism for initial 20 min, and then monomolecular deactivation reaction mechanism.
