Abstract
It is an object of the present invention to provide a storing and/or transferring method of polyalkylene glycol monomers by which the gel-like matter formation and/or decomposition reaction can be satisfactorily inhibited and, as a result, troubles can be prevented from occurring in the production process and the performance characteristics or quality of various chemical products can be satisfactorily prevented from being deteriorated. A storing and/or transferring method of a polyalkylene glycol monomer which comprises storing and/or transferring a polyalkylene glycol monomer in the form of an aqueous solution.

A storing and/or transferring method of a polyalkylene glycol ether monomer
- which comprises storing and/or transferring a polyalkylene glycol monomer in the form of an aqueous solution,
- wherein POV of the polyalkylene glycol monomer is at a level not higher than 2,
- and wherein said polyalkylene glycol ether monomer comprises a monomer represented by the following general formula (1):
- in the formula, R1 and R4 are the same or different and each represents a hydrogen atom or a hydrocarbon group containing 1 to 30 carbon atoms;
- R2 represents —CH2—, —(CH2)2— or —C(CH3)2—;
- R3O are the same or different and each represents an oxyalkylene group containing 2 to 18 carbon atoms;
- and m represents the average number of moles of the oxyalkylene group represented by R3O as added and is a number of 15 to 300.
