| Abstract: | The study of gas phase polymerization of butadiene on supported rare-earth catalyst was carried out. A self-cleaning stirred bed reactor with double axes was designed, especially for solving the problems of l,4-cis-polybutadiene particles' agglomeration and sticking to the walls of reactor. The proper conditions of polymerization were determined. The effects of temperature and monomer pressure on polymerization rate, molecular weight and its distribution were investigated experimentally. The results indicated that the polymerization rate depended upon monomer bulk concentration on lst order. The overall reaction activation energy was estimated. |
