| titleOfInvention | Continuous flow process for the polymerization of an alkylene oxide |
| abstract | The present invention concerns a continuous-flow process for the polymerization of an alkylene oxide comprising the following steps: (a) Mixing an alkylene oxide (1) with a monomer solvent (12), to form a monomer solution (121 ); wherein the monomer solvent is a polar aprotic solvent (b) Forming a reaction mixture (3) by mixing the monomer solution with an anionic initiator (2) selected among the alkali or alkaline-earth alkoxides of general formula R-O-M, wherein, • R is a straight, branched or cyclic alkyl chain, an heterocycle, a glycol or a combination of two or several of these, • O is oxygen, and • M is or comprises an alkali, an alkaline-earth metal or salt thereof; (c) Allowing the reaction mixture to react for a polymerization time, t, comprised between 1 s and 60 min, at a polymerization temperature, T, comprised between 0 and 100°C, and at a polymerization pressure, P, comprised between 1 and 20 bar above atmospheric pressure, thus forming a polymerized solution (5); (d) Separating the solvent (5s) from the polymerized alkylene oxide (5p). |
