Sinopec recently announced that a breakthrough has been made in the National Key R&D Program "Key Technologies for the Industrialization of High-Performance Synthetic Rubber". The project team has recently completed the compilation of a thousand-ton-level basic process data package for the butyl rubber branching agent with independent intellectual property rights, and built China's first star-shaped branched butyl rubber industrial siding device, and completed the water intermodal transport test, and it has the conditions for starting up.

The project addresses the problems of Chinese tires with low fuel efficiency, low safety levels, and short service life of the vulcanization bladder for core components of tire manufacturing. The project focuses on the molecular design of functionalized solution polymerized styrene butadiene rubber and its sequence structure control principle, the disassociation mechanism of rare earth catalyst active centers, and Scientific issues such as the mechanism of high-cis directional reversible chain transfer polymerization of butadiene, the primary/secondary bromination reaction mechanism of bromobutyl rubber in high-efficiency micro-mixing flow fields, breakthroughs in molecular design and controllable synthesis of high-performance rubber materials, and key equipment And key technologies such as engineering, tire and capsule manufacturing formulas and production processes, to realize the industrialization of high-performance synthetic rubber.

Up to now, the project has established the world’s first 10,000-ton-class butyl rubber bromination micro-reaction industrial production device, breaking the monopoly of multinational companies in the core reaction equipment of halogenated butyl rubber, and pioneering micro-chemical technology in the field of synthetic rubber. The application is a precedent; the formula and process for manufacturing long-life curing bladder have been developed to extend the service life of curing bladder to 613 times, far exceeding the industry average of 400 times.
