<p>Provided are: a graft polymer which is good for effective utilization of glycerol and is useful in various fields, particularly, for use in a cement admixture; a cement admixture and a cement composition each of which contains the same; and a manufacturing process by which the graft polymer can be efficiently manufactured. A graft polymer for use in a cement admixture, obtained by graft-polymerizing a monomer component which comprises a monomer having an ionic group and/or an ester thereof onto a glycerol.</p> |
