| titleOfInvention | A method for preparing polyisoprene by steam cracking C5 naphtha fraction |
| abstract | The invention relates to the field of catalytic polymerization, and discloses a method for preparing polyisoprene from steam-cracked C5 naphtha fractions. The method comprises: sequentially performing crystallization, filtration and distillation on the steam-cracked C5 naphtha fractions to obtain a decycled polyisoprene The product of pentadiene; then under the polymerization reaction conditions, the product of said decyclopentadiene is contacted with the rare earth catalyst composition, and the rare earth catalyst composition contains a rare earth metal organic compound, an alkylating agent and A halogen-containing compound, the rare earth metal organic compound has a structure represented by formula (I). The foregoing method provided by the present invention can obtain high-yield polyisoprene products from the isoprene-rich steam cracked C5 naphtha fraction, and the obtained polyisoprene products have cis-1,4- Advantages of high structure content and narrow molecular weight distribution. |
