摘要

The integrated deconvolution estimation model (IDEM) can be used to estimate the reactivity ratios of multiple-site-type catalysts used to make ethylene/α-olefin copolymers, such as heterogeneous Ziegler-Natta and Phillips catalysts. The estimation process combines high-temperature GPC and ~(13)C NMR data to find the reactivity ratios per site type. The IDEM is applied to two sets of ethyl-ene/1-butene copolymer samples made with an industrial TiCl_4/MgCl_2 catalyst in the presence and absence of hydrogen. A sensitivity analysis for parameter estimation is developed and the effect of the presence of hydrogen on the reactivity ratio per site type is quantified for the first time for this copolymerization system.
