Abstract

Abstract: An experimental apparatus composed of microscope, video camera. image-processing, and mini
reactor which can be used for real-time measurement of the growth of polymer particle in gas
phase polymerization was built up to carry out dynamic study of gas phase polymerization of
butadiene by heterogeneous catalyst based on neodymium(Nd). The studies of the shape
duplication of polymer particles and catalyst particles and the growth rate of polymer
particle were made. Results show that the apparatus and procedure designed can be well
utilized to make dynamic observation and data collection of the growth of polymer particle
in gas phase polymerization. A phenomenon of shape duplication of polymer particles and
catalyst particles was observed by the real-time measurement. The result also concludes that
the activity of individual catalyst particle is different, and the effect of reaction
pressure on the growth of polymer particle is significant.

Key words: gas phase polymerization, butadiene, particle growth, dynamic study
