China synthetic natural rubber technology to obtain major breakthrough

The Chinese Academy of Sciences Changchun Institute of applied chemistry relevant responsible person said, the national science and technology support program, "863" project support, synthetic natural rubber - rare earth isoprene rubber technology has made significant achievements, the achievements in the world leading level.

Our country is a natural rubber consuming country, the annual consumption of more than 3800000 tons. At the same time, our country is a natural rubber resource poor countries, the annual output of only 600000 tons, self-sufficiency rate of less than 1/4.

Rare earth isoprene rubber is composed of isoprene with rare earth catalyst CIS polymerization, because of their structure and properties and natural rubber is approximate, it is also called synthetic natural rubber, synthetic rubber instead of natural rubber is the most ideal. The Chinese Academy of Sciences Changchun Institute of Applied Chemistry of synthetic rubber laboratory through innovative research, the development of rare earth isoprene rubber became the isoprene rubber at home and abroad application performance is most close to the natural rubber, and the first rare earth isoprene rubber and natural rubber vulcanized synchronous speed, the realization of arbitrary proportion of rare earth isoprene rubber to natural rubber substitution. They successfully developed high activity, high CIS orientation of the rare earth catalyst system, greatly reduces the cost of the catalyst; method of double olefin coordination reversible chain transfer polymerization, improve the re utilization; development of advanced adiabatic polymerization technology, bonding technology of high viscosity glue reduction, energy saving condensation booster injection technology and other 15 patents, proprietary technology, advanced technology integrated reactor, advanced automatic control and energy saving and environmental protection, chemical industry, the formation of China's first million tons of rare earth isoprene rubber production technology packages, laid the foundation for the acceleration of rare earth isoprene rubber the size of China's industrialization.
