摘要

本文系统地研究了齐格勒-纳塔催化剂在乙烯与1-丁烯和1-己烯气相共聚过程中，气相组成对反应性比估计的影响。研究结果表明，如果用一个现实的状态方程来估计多组分在气相中的共溶和抗溶效应，则可以从任何数量的实验中获得唯一的反应性比对值。然而，研究发现，仅使用二元溶解度数据，忽略化学惰性物质对溶解度的影响，将导致依赖于组成的反应性比对的估计。

Estimation of Reactivity Ratios for Olefin Polymerization Catalysts—On the Importance of Thermodynamics

A systematic study of the impact of gas phase composition on the estimation of the reactivity ratios of a Ziegler–Natta catalyst during the gas phase copolymerization of ethylene with 1-butene and 1-hexene has been carried out. The results of the study show that if one uses a realistic equation of state to estimate the co- and anti-solubility effects of multiple species in the gas phase, one can obtain a unique value of the reactivity ratio pair from any number of experiments. However, it is found that using only binary solubility data and ignoring the impact of chemically inert species on solubility will lead to the estimate of composition-dependent reactivity ratio pairs.
