An acrylic polymer containing at least one terminal group of general formula (I), <CHEM> in the molecule and having a number-average molecular weight of 300 to 100,000; and a process for the preparation of the polymer, (where R<1> is hydrogen or methyl; and X<1> is hydrogen, alkali metal or ammonium). The invention provides acrylic polymer free from discoloration, excellent in chelating power, and biodegradable, a builder comprising the polymer, a detergent composition comprising the builder and a surfactant, a dispersant comprising a salt of the polymer, and processes for preparing them efficiently. <IMAGE> |
