Abstract:
1. A polymerizable polyoxyalkylene monoalkyl ether derivative prepared by using a polyoxyalkylene monoalkyl ether represented by formula [1] as a raw material: wherein R wherein a chromatogram of the polyoxyalkylene monoalkyl ether obtained in accordance with gel permeation chromatography which exhibits a relation between an intensity of a refractive index obtained by a differential refractometer and an elution time satisfies a relation expressed by equation (A): wherein S 1 represents an area under a portion of the chromatogram from start of elution to an earliest elution time when the intensity of a refractive index has a value of L/3, L representing a shortest distance between a greatest maximum point of the intensity of a refractive index and a base line, and S 0 represents an area under a portion of the chromatogram from start of elution to an elution time when the intensity of a refractive index has the greatest maximum value, wherein said polymerizable polyoxyalkylene monoalkyl ether derivative is represented by formula [3]: wherein R1, AO and n are as defined above, and R3 represents acryloyl group or methacryloyl group.
