<p>PROBLEM TO BE SOLVED: To provide a polyalkylene glycol chain-containing polymer composition which, when mixed in a concentrated liquid detergent, has more improved resoiling preventive performance than before, and to provide a method for producing the same.SOLUTION: Provided is a polyalkylene glycol chain-containing polymer composition comprising a structure containing as essential components: a structural unit (a) derived from a one-terminal modified polyalkylene glycol compound (A) represented by a specific structure; a structural unit (b) derived from a (meth)acrylic acid-based monomer (B); a structural unit derived from a polybasic carboxylic acid-based monomer (C); and a structural unit (d) derived from a sulfonic acid group-containing monomer (D) of a specific structure. Relative to a total of 100 parts of structural units derived from all compounds and monomers which form the polyalkylene glycol chain-containing polymer composition, the composition contains 15-60 parts of the structural unit (a), 10-80 parts of the structural unit (b) and/or the structural unit (c), and 5-30 parts of the structural unit (d).</p> |
