PROCESS FOR MANUFACTURING A PELLET-SHAPED NONIONIC ALKYLENE OXIDE RESIN

摘要

An object of the present invention is to provide a manufacturing process by which a pellet-shaped nonionic alkylene oxide resin can be obtained in a manner which is excellent in stability, economical efficiency and productivity and easy, wherein the pellet-shaped nonionic alkylene oxide resin, as a high-molecular material useful in a variety of applications, has a suitable molecular weight Mw and physical properties and is also excellent in the stability of the physical properties and further is also excellent in the handling property after the manufacture. As a means of achieving this object, the process for manufacturing a pellet-shaped nonioni c alkylene oxide resin, according to the present invention, comprises the step s of: obtaining a nonionic alkylene oxide resin having fluidity by volatilizing a solvent from a nonionic alkylene oxide resin solution obtained in advance by solutio n polymerization; and then pelletizing the nonionic alkylene oxide resin havin g fluidity.
