POLYCONDENSATION PRODUCT CONTAINING PHENOLIC COPOLYMER AND DISPERSANT FOR HYDRAULIC COMPOSITION CONTAINING THE SAME
[Problem] To provide a new polycondensation product containing a phenolic copolymer and useful for a hydraulic-composition dispersant that has stable dispersability regardless of the types of impurities in an aggregate, and can obtain a prescribed fluidity. [Solution] A polycondensation product including a copolymer obtained by polycondensing a monomeric mixture that includes compounds A to D respectively represented by formulas (A) to (D). A hydraulic-composition dispersant containing said polycondensation product or said copolymer. (In the formulas, A1O, A2O, A3O, and A4O each represent a C2-4 alkylene oxide group, m and n each independently represent a number from 0 to 300 and m+n=1, p and q each independently represent a number from 1 to 300, X represents a hydrogen atom, an alkyl group, or a C1-24 acyl group, R0 and R1 each represent a hydrogen atom, an alkyl group or an alkenyl group, Y1 and Y2 each independently represent a hydrogen atom, a phosphoester group, or a sulfate ester group, Y3 represents a phosphoester group or a sulfate ester group, R2 represents a hydrogen atom, a carboxyl group, a C1-10 alkyl group, a C2-10 alkenyl group, a phenyl group, a napthyl group, or a heterocyclic group, and r represents a number from 1 to 100.)
