PROBLEM TO BE SOLVED: To provide a method for stably producing a polymer builder which can be stably mixed to a liquid detergent containing a surfactant in high concentration and having excellent color and perfume of a solution. SOLUTION: When the polymer builder for a detergent is produced by polymerizing a specified unsaturated carboxylic acid-based monomer (I) represented by general formula (I) and a specified allyl ether-based monomer (II) represented by general formula (II) in a liquid reaction medium in the presence of a polymerization initiator, 1 to 10 mol% persulfate to total number of moles of the monomer (I) and the monomer (II) is used as the polymerization initiator and a liquid reaction medium containing≥15 wt.% lower alcohol in a total liquid reaction medium is used as the liquid reaction medium.
