    Abstract: PURPOSE: A monomer for preparing a calcium ion-sequestering polymer is provided to improve the calcium ion-sequestering property of a water-soluble copolymer in a water-soluble system. CONSTITUTION: A monomer for preparing a calcium ion-sequestering polymer is represented by chemical formula 1. In chemical formula 1, R1 is hydrogen or methyl, and n is 1~10. A method for preparing the monomer comprises the steps of: reacting alkoxyethanol of chemical formula 3 with epichlorohydrin in a base and a reaction catalyst of chemical formula 4 or 5 to prepare a compound of chemical formula 2; and reacting the compound of chemical formula 2 with an acrylic acid or methacrylic acid in the presence of an acid catalyst to prepare a monomer of chemical formula 1.

    Abstract: PURPOSE: A polymer composition is provided to efficiently prepare polymers using specific monomers and to ensure higher calcium ion sequestering effects than existing polyacrylic acids. CONSTITUTION: A polymer composition for sequestering calcium ions comprises a monomer of chemical formula 1 and a (meth)acrylic acid monomer. In chemical formula 1, R1 is hydrogen or methyl and n is 1~10. In chemical formula 2, R2 is hydrogen or methyl, and R3 is hydrogen, sodium, potassium or ammonium. The polymer composition further includes one or two or more selected from maleic acid, maleic anhydride, and 2-methoxypolyethoxyethyl (meth)acrylate.
