In August 2022, triisobutyl aluminum, the product of our company, and the products of two well-known foreign enterprises carried out nickel catalyzed butadiene polymerization experiments respectively. From the comparison between the data results of polymerization experiment and the physical and mechanical properties of polymer, the test data of our products are the same as that of foreign products.
