Abstract

Online near-infrared spectroscopy technique is employed to investigate the kinetics of the anionic polymerization of butadiene with n-butyllithium initiator in the presence of the microstructure modifier 1,2-diethoxypropane (DEP) in cyclohexane solvent. A phenomenological kinetic model is developed to describe the anionic polymerization process in the presence of DEP, and its influence on the microstructure of polybutadiene under different conditions is determined.
