Production of 1,2- low molecular weight polybutadiene

摘要

This paper introduces commercial production technology of 1,2- Low molecular weight polybutadiene, which apply anion polymerization theory adopting sodium-naphthalene as initiator and toluene as a chain transfer agent, its production and product features has been introduced also. Two patents of the production process, i.e. specific polymerization technology with high monomer concentration and removal of trace water in THF by using common distillation tower have been illustrated.
