On February 8, the 3,000-ton/year industrial demonstration plant for high-regularity polybutylene-1, developed with the technical team from the Beijing Research Institute of Chemical Technology, was successfully commissioned at Zhenhai Refining & Chemical Co., where it operated at full capacity for 72 hours in a continuous and stable manner. This successful drive marks a significant advancement by Sinopec in the field of high-end synthetic new materials, effectively filling a technical gap in China. Sinopec has become the fourth company in the world and the first in China to possess the capability for continuous, stable production of polybutylene-1, thereby breaking the long-standing monopoly of foreign products in this high-performance polymer market and effectively raising Sinopec’s technical level in polyolefin production.
Polybutene-1 is known as the \"gold of plastics\"; it boasts excellent creep resistance, stress cracking resistance, and impact strength, making it suitable for use in a wide range of applications. China lacks similar homogeneous bulk olefin polymerization technologies; the technical and product barriers in this area have yet to be overcome, and domestic high-end polybutylene-1 technologies and products have long been under foreign monopoly. The Beijing Research Institute of Chemical Technology focuses on addressing **needs as a guiding principle, making full use of the advantages of collaborative efforts in the field of new materials. It brings together researchers from various units such as the New Product Development Institute, the Materials Science Institute, the Plastic Processing Institute, and the Polypropylene Institute to form joint task forces for research and development. Since 2010, efforts have been made to overcome various scientific and technical challenges in areas such as the fundamental theoretical research on the structure-activity relationship of polybutene-1, high-performance catalyst technologies, homogeneous bulk olefin polymerization techniques, high-end polybutene-1 products, and advanced polymer devolatilization technologies. Process packages were developed, and through joint efforts with Zhenhai Refining & Chemical Co., SEI, East China University of Science and Technology, and Qingdao Institute of Safety Engineering, the complete set of polybutene-1 technologies was successfully implemented at Zhenhai Refining & Chemical Co. This technology breaks the monopoly of foreign technologies and products, achieving the first domestic technological breakthrough
