Site count: is a high-pressure quenched-flow reactor suitable for kinetic studies of molecular catalysts in ethylene polymerization?

Understanding the kinetics of olefin polymerization with Ziegler–Natta and related catalysts means identifying the main kinetic parameters such as kp and concentration of active sites. The high-pressure quenched-flow technique could be an absolute method for counting active sites and for activation studies of molecular catalysts. A kinetic study of metallocene catalysts and a phenoxy-imine titanium catalyst in the first instants of polymerization is presented in this paper. [ABSTRACT FROM AUTHOR]
