Does anyone know about rare earth rubber? company? technology? Development?

Commonly used free radicals include styrene-butadiene rubber, ionically polymerized butyl rubber, and SBS. Rare earths can be used in the polymerization of butadiene and isoprene to prepare high cis polybutadiene. Replenish: Of course, the current industrialized high cis-butadiene rubber does not use rare earth catalysts.
However, rare earth rubber is very popular in China and has been industrialized abroad.
Rare earths are Chinese resources, and rare earth rubber should be industrialized domestically, but no one has the money to spare, haha
There are many people making rare earth rubber now. It used to be the Changchun Yinghua Institute. Now Jinzhou Petrochemical and Dushanzi Petrochemical have already wanted to industrialize the technology of Changchun Chemical Research Institute. Including rare earth cis-butadiene and rare earth isoprene rubber. The current rare earth isoprene rubber produced by Yanshan Petrochemical is quite impressive. But it is not as good as what Changchun Yinghua did. Qilu Petrochemical is preparing to introduce Russian rare earth isoprene rubber technology. Shandong Luhua Company has produced rare earth isoprene rubber for medical use. Performance is pretty good. Shanghai Gaoqiao Petrochemical is also preparing to join. It was all caused by the clamor for too many C5 resources from relevant experts. hehe
What are the effects of relative molecular weight and molecular weight distribution width that Jinzhou's rare earth cisterns are working on? Want to find a more suitable molecular weight and molecular weight distribution?
By the way, I downloaded a lot of information on rare earth isoprene rubber and rare earth cisbutylene, haha
Upstairs, can you upload the relevant information and share it?
Does anyone know about rare earth rubber? company? technology? Development? Huayu Rubber has already produced rare earth rubber on an industrial scale.
Hope to share it and communicate with each other
Where did BR9000 come from?
