PROCESS FOR MANUFACTURING GRANULATED HYDROPHILIC RESIN

摘要

Granulated hydrophilic resins are manufactured by: an extrusion step to melt and extrude a hydrophilic resin; a cooling step to obtain a solidified resin by solidifying with cooling thus extruded resin through the contact with a metal plate; and a granulating step to obtain a granulated hydrophilic resin by the granulation of thus solidified resin. Thus resulting granulated hydrophilic resins can be used for the extrusion molding and the like.
