Studies on Macro-kinetics of Gas Phase Polymerization of Butadiene with Rare-earth Catalyst

Abstract

Abstract: The study of the kinetics of gas phase polymerization of butadiene with heterogeneous
catalyst based on neodymium (Nd) was carried out. The effects of reaction temperature,
reaction pressure, dispersing medium,and types of catalyst on kinetics of polymerization
were investigated. A kinetic model with two kinds of active sites was proposed. The results
show that the effects of the reaction temperature and the types of dispersing medium and
catalyst on the kinetic performance of polymerization are significant, and that the
combined model of first and second order decay of active site of catalyst can be used to
describe the phenomena.

Key words: butadiene, gas phase polymerization, kinetics, model
