| titleOfInvention | Rare earth styrene derivative/isoprene/butadiene ternary rubber and preparation method thereof |
| abstract | A rare earth styrene derivative/isoprene/butadiene ternary rubber and a preparation method thereof belong to the technical field of high polymer materials, and are prepared by catalyzing styrene derivative, isoprene and butadiene ternary polymerization by a rare earth catalyst, wherein the number average molecular weight is 1 multiplied by 10 4 ‑100×10 4 mol/g. The content of the styrene derivative is 10 to 60 percent and the content of the isoprene is 20 to 70 percent in terms of molar percentage. The content of 3, 4-polyisoprene is 3-79 percent based on 100 percent of the total amount of polyisoprene; the content of 1, 4-polybutadiene is 50% -97% calculated by 100% of total polybutadiene. The styrene derivative at least contains a substituent of a nitrogen atom, an oxygen atom, a sulfur atom, a phosphorus atom and a silicon atom group, and the substituent can be directly connected to the ortho, meta and para positions of the double bond of the styrene derivative; rare earth catalyst is prepared from rare earth complex CpLnR 2 X n And an organoboron reagent. The invention uses the metallocene rare earth complex as the main catalyst, the synthesis is easy, the cost is low, and the obtained ternary rubber can effectively improve the blending performance of rubber and other fillers and improve the performance of the rubber in the processing and using processes. |
