| titleOfInvention | Polyether preparation method, prepolymer preparation method, and modified silicone polymer preparation method |
| abstract | A polyether preparation method which comprises a polymerization step of subjecting a monoepoxide having at least 2 carbon atoms to ring-opening addition polymerization to an initiator having at least one active hydrogen-containing functional group in the presence of a catalyst in a stirring vessel, to obtain a polyether, wherein the stirring vessel is one wherein a stirring shaft rotatable by an external drive source is provided at the center of the stirring vessel; plate-shaped bottom paddles extending in a radial direction of the stirring vessel are mounted on a lower portion of the stirring shaft; lattice vanes each comprising arm paddles extending in a radial direction and strips extending in an axial direction, are mounted on a portion of the stirring shaft above the bottom paddles; and a discharge nozzle as a monoepoxide-supply means for discharging the monoepoxide to at least two locations below the lower ends of the strips. |
