| titleOfInvention | A kind of synthetic method of high-cis lithium system isoprene rubber |
| abstract | The present invention relates to technical field of petrochemical industry, and in particular to a kind of synthetic method of high-cis lithium system isoprene rubber.A kind of synthetic method of high-cis lithium system isoprene rubber, comprises the following steps：The preparation of raw material：Isoprene, n-BuLi, hexamethylene；The synthesis of lithium system isoprene rubber：High purity N is used first 2 Reactor is cleaned 3 times；5ml solvent and 5g isoprene monomers is added into the reactor after cleaning；Start stirred autoclave until well mixed；When temperature reaches initiation temperature, a small amount of n-BuLi imurity-removal is added；A certain amount of n-BuLi initiation reaction is added after removal of impurities, is eventually adding terminator terminating reaction；Above-mentioned glue condenses by vapor, and carries out extrusion dehydration drying.By the isoprene rubber better performances that the synthetic method of high-cis lithium system isoprene rubber provided by the invention is worth, usage time length is pure, to cut yield without gel higher, suitable for promoting the use of a large area. |
