The copolymer for cement admixtures comprises: constitutional unit (I) derived from unsaturated polyalkylene glycol ether monomer (a) having an alkenyl group having 5 carbon atoms and an oxyalkylene group having 2 to 18 carbon atoms with an average addition number of moles of the oxyalkylene groups to be in the range of 10 to 300; and constitutional unit (II) derived from unsaturated monocarboxylic acid monomer (b). The cement admixture includes the copolymer for cement admixtures as an essential component, and may further include a defoaming agent. The cement composition includes the copolymer for cement admixtures, and cement as essential components. The production process for the copolymer comprises: copolymerizing comonomers including unsaturated polyalkylene glycol ether monomer (a) and unsaturated monocarboxylic monomer (b) as essential components by use of a chain-transfer agent, and/or adjusting pH of a resultant reaction mixture to not less than 5 after the copolymerization.

摘要： A method for the production of an esterified product is provided which affords an esterified product with high quality by repressing, during the esterification reaction of an alcohol with (meth)acrylic acid, the occurrence of impurities, particularly gel, to be formed owing to the polymerization of the alcohol and the (meth)acrylic acid as raw materials, the esterified product consequently formed, or the mixture thereof. Specifically, a method for the production of an esterified product of this invention comprises esterifying an alcohol represented by the following formula (1):

R 1 O(R 2 O) n H (1)

wherein R 1 represents a hydrocarbon group of 1 to 30 carbon atoms, R 2 O represents an oxyalkylene group of 2 to 18 carbon atoms, providing that the repeating units, R 2 O, may be the same or different and that when the R 2 O's are in the form of a mixture of two or more species, the repeating units, R 2 O, may be added either in a block form or in a random form, and n represents an average addition mol number of oxyalkylene groups and is in the range of 0 to 300, with (meth)acrylic acid in a dehydrating solvent in the presence of an acid catalyst and a polymerization inhibitor, wherein a reaction temperature during the esterification reaction is not higher than 130 °C and a circulation speed of the solvent during the esterification reaction is not less than 0.5 cycle/hour.

摘要： The invention provides: a cement admixture which has excellent cement dispersibility and can afford high slump retainability; and a cement composition which has excellent cement dispersibility and high slump retainability. The cement admixture comprises a polycarboxylic acid as an effective component, wherein the polycarboxylic acid is obtained by a process including the steps of: charging "a" parts by weight of a polyalkylene glycol (A) and "b" parts by weight of a (meth)acrylic acid monomer (B) into a reactor in the range of {(a/n 1/2 )/b} × 100 ≤ 200 , wherein n is an average molar number of the added oxyalkylene groups in the polyalkylene glycol (A) and is a number of 1 to 300; carrying out an esterification reaction of the resultant mixture in the reactor, thus obtaining a polyalkylene glycol (meth)acrylate (C); and copolymerizing the resultant polyalkylene glycol (meth)acrylate (C) and the (meth)acrylic acid monomer (B), thus obtaining the polycarboxylic acid.
