| 초록 | Various kinds of olefin polymers are manufactured commercially by using heterogeneous Ziegler-Natta type catalysts in liquid slurry or gas phase polymerization reactors. Quite often, it is desirable to control the average size or size distribution of polymer particles because they may affect the polymerization rate and the mixing of additives in the finishing stage. In addition, costly pelletization stage may be omitted if the particle size distribution can be controlled according to production specifications. This article deals with the development of a particle size distribution model for a continuous slurry polymerization process using a heterogeneous Ziegler-Natta catalyst. The particle size distribution model incorporates the multigrain model (MGM) to describe the growth of polymer particle from the original catalyst particle. We also adopt the concept of multiple active sites to elucidate the broad molecular weight distribution (MWD). The major concern here is the effects of the uniform size or the size-distributed feed catalyst on the yield and the polymer particle size distribution in the reactor. |
