摘要： An object of the present invention is to provide a process which can produce, easily and with good productivity and reproducibility, an ethylene oxide copolymer provided with desired compositional ratios of monomers and a desired molecular weight and further with a desired melting point. As a means of achieving this object, a process according to the present invention for production of an ethylene oxide copolymer is a process comprising a step of polymerizing a monomer mixture including ethylene oxide as a main component, thereby producing the ethylene oxide copolymer, with the process being characterized in that the polymerization step includes at least one step each of the following steps: a step in which only the ethylene oxide is supplied to thus polymerize it; and a step in which the ethylene oxide and another monomer are supplied to thus polymerize them.
