摘要：To provide a polymer having a specific parameter value with a very narrowmolecular weight distribution different from the conventional copolymers despite of apolymer having a polyoxyalkylene chain, and an excellent dispersant for inorganicpowders, particularly a cement addmixture. The polymer (P) in the present invention iscontaining a constitutional unit derived from a polyoxyalkylene chain, and satisfying arange of PD value defined as the following mathematical formula 1: 1
