Title:
METHOD FOR STORING AND/OR TRANSPORTING POLYMER RAW MATERIAL FOR CEMENT ADDITIVE CONTAINING ALKOXY (POLY) ALKYLENE GLYCOL
Document Type and Number:
Japanese Patent JP3910369
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for storing and/or transporting a polymer raw material for a cement additive containing alkoxy (poly)alkylene glycol, capable of sufficiently suppressing the generation of faults at a manufacturing stage and the deterioration of performance and quality of various kinds of chemical products in addition to the cement additive by sufficiently suppressing the formation of gel-like substance and occurrence of decomposition reaction.
SOLUTION: The alkoxy (poly)alkylene glycol is expressed by the following general formula (1); R1O(R2O)nH (1) (in the formula, R1 is 1-30C hydrocarbon group, R2Os, which can be either same with or different from each other, are 2-18C oxyalkylene groups, n is an average addition molar number of the oxyalkylene group expressed by R2O and 0-300) and the storage and/or transportation are performed at solidification point or below.
