The present invention provides a dispersion-retaining agent for a hydraulic composition being excellent in both fluidity retainability and viscosity retainability and further a dispersion-retaining agent exhibiting fluidity retainability and viscosity retainability regardless of the type of hydraulic powder. The present invention relates to a dispersion-retaining agent for a hydraulic composition, containing a copolymer obtained by polymerizing specific monomer 1 represented by formula (1), with monomer 2 represented by formula (2), the corresponding alcohol compound of which satisfies specific physical properties, wherein, in the constituent monomers of the copolymer, the proportion of the monomer 1 is in a specific range, a specified monomers is used as at least a part of the monomer 2, and the proportion of monomers having an acid group or a neutralized group thereof is 5% by weight or less.
摘要:
A temperature control apparatus that controls a temperature of a target object by a heat exchange between a temperature control liquid and the target object. The apparatus includes a pressurizing unit that pressurizes the temperature control liquid to increase a boiling point thereof; a heating unit that increases a temperature of the temperature control liquid to become higher than or equal to a boiling point of the temperature control liquid observed at a normal pressure; and a heat exchanging unit that exchanges heat between the target object and the temperature control liquid whose temperature has been increased to become higher than or equal to the boiling point of the temperature control liquid observed at the normal pressure.

Disclosed in the present invention is a process for preparing a (meth)acrylic acid-based polymer having a stable quality and suitable as a dispersant for cement. That is, the present invention provides a process for preparing a (meth)acrylic acid-based polymer, comprising the steps of the stage 1 of introducing (meth)acrylic acid and a polyalkylene glycol monoalkyl ether at a molar ratio in the range of 3:l to 50:1, subjecting them to an esterification reaction in the presence of an acid catalyst and a polymerization inhibitor and deactivating the acid catalyst with an alkaline agent in order to obtain an esterification product containing a (meth)acrylate and (meth)acrylic acid residues and the stage 2 of copolymerizing the (meth)acrylate and the (meth)acrylic acid residues at a pH value in the range of 1.5 to 3.5.
