Beschreibung
Zusammenfassung:	There is provided a polycondensation product containing a novel phenolic copolymer useful as such a dispersant for hydraulic composition that has stable dispersibility varies depending on of the kind of impurities in an aggregate, and can achieve predetermined flowability. A polycondensation product includes a copolymer obtained by polycondensation of a monomer mixture containing the compounds A to D mentioned the following formulae (A) to (D), and a dispersant for hydraulic composition containing the polycondensation product and the copolymer. (D)R 2 -CHO, HO(CH 2 O) r H or (CH 2 O) 3 wherein A 1 O, A 2 O, A 3 O and A 4 O are each independently a C 2-4 alkylene oxide group; m and n are each independently a number of 0 to 300, and m+n is 1 or more; p and q are each independently a number of 1 to 300; X is a hydrogen atom, a alkyl group, or a C 2-24 acyl group; R 0 and R 1 are each independently a hydrogen atom, a alkyl group or a alkenyl group; Y 1 and Y 2 are each independently a hydrogen atom, a phosphate group, or a sulfate group; Y 3 is a phosphate group or a sulfate group; R 2 is a hydrogen atom, a carboxyl group, a C 1-10 alkyl group, a C 2-10 alkenyl group, a phenyl group, a naphthyl group, or a heterocyclic group; and r is a number of 1 to 100.
