| description | Disclosed is a polymer which has a quite narrow molecular weight distribution that is different from that of a conventional copolymer in spite of the fact that the polymer has a polyalkylene glycol chain, and also has a specific parameter. Also disclosed is a dispersant for an inorganic powder, particularly a cement admixture, which is prepared using the polymer and has an excellent dispersing property. The polymer is a polymer (P) having a constituent unit derived from a polyoxyalkylene chain and has a PD value as defined below: 1 < PD < MD (Formula 1) wherein PD = Mw/Mn, MD = G(n) x Mw + H (n) |
