The polymerization is carried out at a ratio of the average number of moles and is represented by the following formula (a): Macromonomer: compound represented by formula (b): compound represented by formula (d) ) Can be polymerized at a ratio of 0.1 to 400: 0 to 400: 0.1 to 400: 0 to 400: 0 to 400. Particularly preferred is a macromonomer represented by the formula (a): a compound represented by the formula (b): a compound represented by the formula (d): a compound represented by the formula (e) 1 to 100: 0 to 70: 1 to 100: 0 to 150: 0 to 150. If the proportion of the compound represented by the formula (e) or the compound represented by the formula (f) is too low, the dispersing performance is deteriorated. If the ratio is too high, the retaining performance is deteriorated due to the high viscosity.

The polymerization product can be obtained by reacting at 30 to 150 ° C for 0.5 to 150 hours, particularly preferably at 50 to 130 ° C for 0.5 to 80 hours. If the reaction time is too short or too long, the polymerization degree is lowered and the performance is lowered. If the temperature does not reach or exceed a certain temperature during the polymerization, the polymerization may not proceed or the chain may be broken.

In the polymerization of the monomer component, a chain transfer agent and a polymerization initiator may be used. As the chain transfer agent, any appropriate substance can be used. Specifically, thiol chain transfer agents such as thioglycerol, mercaptoethanol, 2-mercaptopropionic acid, 3-mercaptopropionic acid and thiomalic acid can be used. As the polymerization initiator, persulfates such as ammonium persulfate, sodium persulfate and potassium persulfate, peroxide-based polymerization initiators such as hydrogen peroxide and benzoyl peroxide can be used.

The high molecular weight polymer represented by the formula (g) prepared by the above method simultaneously contains an ester-based macromer and an ether-based macromer, and exhibits a high polymerization rate of the ester-based macromer, Due to the polymerization time, a hybrid polymer having excellent dispersibility and workability can be obtained.

In addition, the hybrid polymer prepared as described above may be used alone as a cement fluidizing agent, a mortar / concrete admixture, or an AE / AE water reducing agent that improves work performance or freezing / thawing resistance performance, A shrinkage reducing agent for reducing shrinkage occurring during drying, an accelerator for retarding the setting and curing time, a retarder, a rust inhibitor for inhibiting the corrosion of reinforcing steel by chloride, a separating reducing agent for preventing the separation of cement and aggregate, A waterproofing agent for enhancing waterproofness, a foaming agent for lighter weight by generating bubbles, a foaming agent, and an admixture of a thickener for improving viscous / cohesive action, and may be made of a cement fluidizer and a mortar / concrete admixture.
