A new type of rare earth isoamyl rubber

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences and the China Petroleum Jilin Petrochemical Company scientists and technicians, after more than a year of research and technology, homogeneous rare-earth catalyst to the success of a new type of synthetic rubber isoamyl rare earth, and recently adopted a Chinese oil experts acceptance . The Group believes that the outcome of an internal initiative, a catalyst for the development of technology to reach international advanced level.

Isoamyl rubber for its molecular structure and properties of natural rubber with the closest, also known as "synthetic natural rubber" is a substitute for synthetic rubber to natural rubber in the performance of the best types of plastic. Can be widely used in tires, plastic, rubber hose, and other areas of processing, but in China's synthetic rubber types of plastic, rubber isoamyl production is blank.

In China's rubber consumption reached 300 million tons, ranking first in the world, however, natural rubber production in just over 50 million tons, a huge gap in demand and, in recent years, China's imports of natural rubber and synthetic rubber each year millions of tons Above. To this end, developed as soon as possible with our own intellectual property rights isoamyl rubber, and speed up the industrialization of its size, synthetic rubber to enhance the international competitiveness of China's rubber consumption from the industrial production of rubber Powers power shift has become more and more countries Major strategic needs.

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences is China's first synthetic rubber to carry out R & D units, with strong accumulation of scientific research and technology, human resources, and other advantages. China Petroleum Jilin Petrochemical Company in the aggregate, technology, testing, it is also a strong power, the two sides together, in March 2006 launched a "new type of rare-earth isoamyl small rubber test technology development". After more than a year of hard work, researchers put forward the innovative homogeneous catalyst for the preparation of rare-earth solutions to the uneven over the years due to the catalyst system, measures are not allowed, leading to instability in the products on major issues; by changing the catalyst preparation Way to break through the traditional homogeneous polymerization catalyst of rare earth products of low molecular weight limitations, can develop a synthesis of high molecular weight polyisoprene homogeneous system of rare earth catalyst for the development of "Guo Zihao" rare earth high-quality rubber to provide isoamyl A high-performance materials, has laid an important foundation. On this basis, through the improvement of polymerization processes, and so on, at a high temperature (40 ° C) have successfully synthesized the crystallization of natural rubber and stretch characteristics similar to a new type of high-quality rare earth isoamyl rubber.

According to experts, in recent years as China's ethylene project of continuous development of the C5 fraction of ethylene in a large number of enrichment, and the C5 fraction of isoprene is prepared isoamyl rubber excellent raw materials. To this end, rare earth isoamyl rubber research and development success, not only to address the shortage of natural rubber in China has opened up a new kind of plastic, rubber Isoamyl to speed up the industrialization of laid an important foundation, and can effectively promote the comprehensive utilization of C5 distillate, Its enormous economic and social benefits.
