Abstract

An alkylene oxide derivative represented by formula (1), wherein a ratio Mz/Mw of a weight average molecular weight (Mw) and z average molecular weight (Mz) calculated from a chromatogram obtained by gel permeation chromatography measurement of the alkylene oxide derivative satisfies formula (2) below: Z - [ O - ( P ⁢ O ) a - ( P ⁢ O ) b / ( E ⁢ O ) ⁢ c ] - H ] n ( 1 ) 5 ≦ M z / M w ≦ 60 ( 2 ) where Z, n, PO, EO, a, b and c are as defined herein; a+b+c≥10, and b/c=1/5˜5/1; (PO)b/(EO)c indicates that PO and EO are randomly added; and a random ratio x of PO and EO satisfies 0.1≤x≤1.
