Patent ID: 7026442

Claim:
A storing and/or transferring method of an alkoxy(poly)alkylene glycol-containing material for cement additive polymer which comprises a step of filling a vessel, a step of storing and/or transferring and a step of drawing out, in that order, said alkoxy(poly)alkylene glycol being represented by the following general formula (1); R 1 O(R 2 O) n H (1) in the formula, R 1 represents a hydrocarbon group containing 1 to 30 carbon atoms, R 2 O group represents an oxyalkylene group containing 2 to 18 carbon atoms and each R 2 O group may be the same or different and n represents the average number of moles of the oxyalkylene groups represented by R 2 O as added and is a number of 2 to 300, and said step of storage and/or transfer being carried out at a temperature not higher than the solidifying point of the material for cement additive polymer.
