| Outline of Annual Research Achievements |
Three targets have been set in FY2017 and the achievements are as follows
1. Synthesis of Mg(OEt)2 catalyst supports: The new Mg(OEt)2 synthesis procedure was established with much better repeatability using the existing parallel reactor system. More than 60 samples of Mg(OEt)2 were synthesized in FY2017.
2. Synthesis of catalysts: The setup of catalyst preparation reactor system was completed based on an in-house design suspended magnetic stirrer with temperature control system using oil circulator. The system enables up to 12-parallel catalyst preparation with high repeatability.
3. Multilateral characterization: The new characterization methods were introduced to accelerate the analysis and to improve the accuracy, i.e. the analysis of organic donor by FT-IR was replaced by 1H NMR.

2: Research has progressed on the whole more than it was originally planned.
Reason
The project progressed smoothly and the quality of data is better than expected.

| Strategy for Future Research Activity |
Research plan in FY2018 will focused on setting up the high pressure parallel reactor system and the evaluation of catalyst performance. Within the first half of FY2018, the design of the polymerization system will be finalized. After confirming the reproducibility of the system, the catalysts obtained from FY2017 and newly prepared catalysts in FY2018 will be tested. The properties of produced polymer will be evaluated based on the standard analysis and the structure-performance relationship will be established.

| Causes of Carryover |
Unused budget for article cost was original planned for the modification of in-house 24-parallel reactor system (such as reactant feeding and decantation systems) to reduce the manual operation. However, it was found that the constraint from the original design of the reactor will make the practical operation more complicated. Therefore, the reactor system was kept as its original state. The remaining budget will be used for the setup of high pressure parallel reactor system for olefin polymerization.
