China's synthetic rubber industry started from independent research and development, through the introduction of technology development, and rely on independent innovation to continuously improve, enrich and grow up, in China's three major synthetic materials, synthetic rubber from raw materials to the product of independent innovation technology achievements is the most.

Since November 1958 in Chongqing Changshou Chemical Plant chloroprene rubber industrialized production, after several generations of struggle, China's synthetic rubber industry has crossed 60 years of brilliant development.

At present, China's synthetic rubber plant capacity, production and consumption, ranked first in the world, the main varieties of synthetic rubber all form a complete set of technology with its own technology.

China Synthetic Rubber Industry Association recently released the synthetic rubber industry's main independent innovation achievements:

4. Independent development of industrialized technology of ethylene propylene rubber

In 1960, the Beijing Research Institute of Chemical Industry began research on the synthesis of ethylene propylene rubber, 1960-1985 period, the use of 50 tons / year expansion of the pilot plant to prepare a small amount of ethylene propylene rubber to meet the needs of the military sector. Among them, the ethylene propylene rubber with resistance to 752 media won the third prize of National Scientific and Technological Progress.

In 1972, a 2,000-ton/year industrial low-pressure polymerization production unit was built in the synthetic rubber plant of Lanhua Chemical Company, and a joint technical research was carried out from 1975 to 1977, which resulted in the trial production of low-molecular-weight binary ethylene-propylene copolymers used as viscosity-index improvers for oils. 1992 saw the appraisal of the scientific research achievements of ethylene-propylene rubber organized by the Ministry of Chemical Industry.

In September 1997, Jilin Petrochemical Company used the introduced technology to build 20,000 tons/year ethylene-propylene rubber plant, and since 2001, the organization has been upgrading the technology of ethylene-propylene rubber and independently developed 40,000 tons/year ethylene-propylene rubber process package, and achieved industrial production in 2014, and developed a total of 13 grades of ternary rubber as well as OCP and other new products.

5. Independent development of industrialized technology of butyl rubber

In 1966, Lanzhou Research Institute of Chemical Technology started the laboratory research on the synthesis of butyl rubber by slurry polymerization process, and in early 1979, it built a pilot plant with a scale of 100 tons/year and a cold-mode test plant with a polymerization kettle volume of 100L.

During 1979-1983, the process, equipment, engineering, control, analysis and testing, as well as processing and application of the research, completed a 10,000-ton butyl rubber industrial plant technology and economic evaluation.

At the end of 1999, Yanshan Petrochemical Company built a 30,000-ton/year butyl rubber plant using the polymerization technology of PI Company; because of the lack of experience in industrial production of this technology, it was transferred to normal production in 2002 after joint research on polymerization and process technology in cooperation with Beijing University of Chemical Technology.

In 2006, “Isobutylene Controlled Cationic Polymerization and Butyl Rubber Polymerization New Process Technology” won the Second Prize of National Technology Invention Award. in October 2010, SINOPEC Yanshan Petrochemical Company put into production 30,000 tons/year of bromobutyl rubber plant built with independent technology.

6. Independent development of industrialization technology of isoprene rubber

In the 1960s, Changchun Institute of Applied Chemistry and Jihua Research Institute of titanium-based isoprene rubber research and scale-up tests, began to shift to better performance of rare earth isoprene rubber synthesis research in 1970, and built a 100 tons / year of pilot plant in Beijing YANHUA Synthetic Rubber Plant 10,000 tons of cis-butadiene rubber production unit for assessment of trial production.

In May 2010, Zibo Luhua Hongjin New Material Co., Ltd. used its own technology to put into production 15,000 tons/year isoprene rubber production unit in Maoming Luhua.

In October 2010, Qingdao Icos New Material Co., Ltd (under the National Rubber and Tire Engineering and Technology Research Center) independently developed 30,000 tons/year of isoprene rubber has also achieved industrialization, and in 2014, 40,000 tons/year of isoprene rubber plant was built in Fushun Icos.

In 2013, SINOPEC Yanshan Petrochemical Rubber Plant built a 30,000 tons/year cis-isoprene rubber production plant using Yanshan Petrochemical Research Institute's own technology.

In 2000, “Synthesis and Application Development of High-trans-1,4-Polyisoprene” developed by Qingdao University of Science and Technology was awarded the Second Prize of National Technology Invention Award, and in 2012, it was realized 10,000-ton industrial production in Qingdao Dipai New Material Co.
