    • A polymerizable polyoxyalkylene monoalkyl ether derivative prepared by using a polyoxyalklene monoalkyl ether which gives, in gel permeation chromatography, a chromatogram which satisfies a relation expressed by an equation: S1/S0≦0.15, wherein S1 represents the area under a portion of the chromatogram from the start of elution to the earliest elution time when the intensity of the refractive index has a value of L/3, L representing the shortest distance between the greatest maximum point of the intensity of the refractive index and the base line and S0 represents the area under a portion of the chromatogram from the start of elution to an elution time when the intensity of the refractive index has the greatest maximum value; a process for producing the above ether comprising adjusting the content of water in a reactor, which is used in addition polymerization of alkylene oxides with addition to a monohydric alcohol, so as to satisfy an equation: Wi×(Cf−Ci)/V≦10, wherein the content of water in the reactor is obtained by placing a solvent having a content of water Ci (ppm) in an amount Wi (g) in the reactor having an inner volume V (ml), stirring the solvent to clean the reactor, removing the solvent from the reactor and obtaining a content of water Cf (ppm) in the removed solvent.
    • 通过使用聚氧化烯单烷基醚制备的可聚合的聚氧化烯单烷基醚衍生物,所述聚氧化烯单烷基醚在凝胶渗透色谱法中得到满足由下列公式表示的关系的色谱图:S&lt; 1&lt; > <= 0.15,其中S 1表示当折射率的强度为L / 3时的从洗脱开始到最早洗脱时间的色谱图的一部分的面积,L 代表折射率强度的最大最大点与基线之间的最短距离,S O表示从洗脱开始到洗脱时间的部分色谱图下的面积 折射率的强度具有最大的最大值; 一种制备上述醚的方法,包括调节反应器中的水含量,该反应器用于加成环氧烷与一元醇的加成聚合,以满足下式:Wix(Cf-Ci)/ V <= 10,其中反应器中的水含量是通过将具有内容积V(ml)的反应器中具有含量为Wi(g)的水分量(ppm)的溶剂置于内部体积V(ml)中,搅拌溶剂来清洗 反应器中,从反应器中除去溶剂,并在去除的溶剂中获得水含量Cf(ppm)。
