摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a resin pellet capable of stably effectively manufacturing an ethylene oxide-butylene oxide-based copolymer resin pellet having a low crystallization temperature of 10°C to 60°C, and to provide a resin pellet obtained by this method.;SOLUTION: The molten ethylene oxide-butylene oxide-based copolymer is shaped into predetermined thickness by extrusion. The extruded molten resin is made to contact a metal surface having a temperature of not higher than the crystallization temperature (Tc) of the resin to be cooled and solidified. Then the solidified resin is cut into pellets.;COPYRIGHT: (C)2005,JPO&NCIPI
