It is effective for saving energy to develop a polypropylene manufacturing technology without a pelletizing step. Novel clay mineral supported metallocene catalyst technologies to produce PP powders having good morphology and large particle size which can be handled like conventional pellets were developed. Producing technologies for catalyst supports using montmorillonite with large particle size and narrow particle size distribution appropriate for the production of large particle size PP powders were developed. Polymerization technologies for large particle size PP powders utilizing the catalysts mentioned above were developed, and powders with targeted size and shape could be obtained.
