| Outline of Final Research Achievements |
In this research, the application of a high-throughput approach using in-house developed parallel reactor systems for the synthesis of Ziegler-Natta catalysts was successfully demonstrated, aiming at unveiling the quantitative structure-performance relationship in olefin polymerization. The developed systems enabled the parallel synthesis of magnesium ethoxide as a support material and catalysts with the excellent reproducibility and particle quality for the first time. The obtained catalysts were parameterized by means of various characterization techniques. Due to the complexity of the catalyst structure, it was found that the performance of the catalyst was hardly explained on the basis of one-to-one relation. On the other hand, the statistical analysis based on the multiple linear regression model reasonably explained the performance with adequate prediction ability.
