【Ten Years of Great Progress in Chemical Technology】Catalysts for electron-donating high-melt-strength polypropylene from 2015 to 2023

Thread Content

The catalyst technology for high-melt-strength polypropylene developed by the Beijing Research Institute of Chemical Technology has passed evaluation. There has been significant progress in chemical technology over the past decade; China’s prosperity and strength are truly admirable. By contributing our ideas, we can foster more active participation from everyone. With you here, Haichuan becomes even better – we welcome everyone to participate more actively in discussions on this forum. It’s hot in July, so be careful to prevent fires. ---------------------------------------------- Recently, the “catalyst for high-melt-strength polypropylene based on new structural electron-donating agents” developed by Sinopec’s Beijing Research Institute of Chemical Technology was evaluated by the group company’s science and technology department, and it was found to be at an internationally leading level. Internal electron donors are one of the key factors in catalysts, significantly influencing the performance of the catalyst as well as the microstructure, mechanical properties, and processability of the polymers. For nearly 20 years, Beihua Institute has been deeply involved in the field of internal electron donors, continuously pursuing innovation, and has become one of the few research institutions in the world to have commercialized two types of original internal electron donors. Based on their mastery of the new generation of internal electron-donating group control technology, they developed the BCZ-308 catalyst with excellent comprehensive performance. This catalyst is produced by Sinopec Catalyst Company and has been successfully applied in the 250,000-ton/year Innovene gas-phase plant at Shanghai Sinopec; it enables the direct production of high melt strength polypropylene within the reactor. The melt strength of this product is significantly higher than that of imported products, enabling it to meet the performance requirements of downstream enterprises for processing techniques such as compression molding, blow molding, and film blowing. It can be used to produce high-performance packaging materials, waterproof membrane release films, and other products, yielding significant economic and social benefits. (
