my country's rare earth rubber catalyst engineering technology has made another breakthrough

Recently, it was learned from the Research Institute of Petrochemical Industry that the first domestic single-active center rare earth metal catalyst independently developed by the special expert innovation team of the Petrochemical Institute was successfully prepared in the continuous polymerization pilot test of butadiene rubber in Dushanzi Petrochemical Company
.
The polymerization efficiency is about 20 times that of the current mainstream ternary rare earth catalysts, and it can produce various grades of high-performance rare earth butadiene rubber, achieving a new breakthrough in the scientific research and engineering technology of rare earth rubber catalysts in China
.

Compared with the mainstream ternary rare earth catalyst, the single-site rare earth catalyst has higher catalytic efficiency, and the obtained butadiene rubber product has better physical and mechanical properties, and can reduce rolling resistance, reduce heat generation, and improve wear resistance
.
The parameters of the continuous polymerization pilot test show that the content of cis-1,4 in the produced rare earth cis-butadiene rubber is more than 98%, and the molecular weight distribution width is adjustable in the range of 2.
0 to 3.
0.
All indicators are at the leading level in the domestic industry
.
In addition, during the operation of the device, the glue liquid is transported smoothly, without glue hanging, and it can still operate continuously and stably in the extremely high Mooney viscosity range (greater than 110)
.
The popularization and application of this rare earth catalyst is expected to greatly improve the performance of rare earth butadiene rubber, increase the added value of products, and improve the stability and safety of production
.

This catalyst technology is the original achievement of the innovation team of specially-appointed experts from the Petrochemical Institute
.
The success of this continuous polymerization pilot test has opened up the application process of single-site rare earth metal catalysts in continuous polymerization devices, laid a solid foundation for subsequent industrial tests, and promoted the follow-up research and development of the "rare earth-solution polymerization" platform technology.
The development of a variety of new elastomeric materials based on C4 and C5 raw materials has paved the way
