| titleOfInvention | Polyethers and Manufacturing Method Thereof |
| abstract | When manufacturing polyethers using a composite metal cyanide complex catalyst, the molecular weight distribution of the obtained polyethers can be made narrower. In the presence of a complex metal cyanide complex catalyst, a ring-opening addition polymerization of a cyclic monomer such as alkylene oxide to an initiator having a hydroxyl group is carried out to produce polyethers having one or more hydroxyl groups. The manufacturing method of polyether which has a process. Initial stage: In the reaction system containing an initiator and a composite metal cyanide complex catalyst, 5? A step of reacting by supplying a cyclic monomer in an amount of 20 parts by mass. At that time, the temperature of the reaction system at the time of starting supply of the cyclic monomer was 120? It is 165 degreeC, and the maximum temperature of the reaction system after cyclic monomer supply is 15 degrees from the temperature of the said cyclic monomer supply start time. 50 ℃ high. Polymerization Step: A step of ring-opening addition polymerization by supplying a cyclic monomer to the reaction system after the initial step. |
