| titleOfInvention | Polyfluoroalkyl diol and preparation method thereof |
| abstract | The invention relates to polyfluoroalkyl diol and a preparation method thereof. The preparation method disclosed by the invention comprises the following steps: performing ring-opening addition reaction on polyethylene polyamine and glycidyl in a polar solvent to generate polyamine diol, then adding olefin-containing a fluoroalkyl terminal, and utilizing carbon-carbon double bonds of the olefin-containing the fluoroalkyl terminal and a primary amino group and a secondary amino group in the polyamine diol to performing addition reaction through addition reaction between carbon-carbon double bonds of the olefin-containing the fluoroalkyl terminal and a primary amino group and a secondary amino group in the polyamine diol so as to obtain the polyfluoroalkyl diol. The reaction is completed by adopting a one-pot method, the preparation process is simple and convenient, the reaction conditions are mild, byproducts are avoided, and the preparation method is suitable for industrial production. The obtained polyfluoroalkyl diol is an alcohol compound with 2 degrees of functionality, has the characteristics of high fluorine content and determined reactivity and can be used as a synthetic fluoroalkyl modified polyurethane chain extender. |
