<P>PROBLEM TO BE SOLVED: To provide a polymer-containing composition, which contains a polyalkylene glycol polymer and can be suitably used as a cement admixture, since the composition useful for various purposes exhibits well-balanced cement dispersibility and cement retaining properties in a cement composition when used as a cement admixture especially, can improve conditions of the cement composition, and can reduce an admixture addition amount. <P>SOLUTION: The polymer-containing composition includes two or more kinds of a polyalkylene glycol polymer (A) and a polyalkylene glycol polymer (B), which are different in the acidity in the structural unit derived from a vinyl monomer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
