Biodegradable poly(maleic anhydride‐ co ‐taurine) was synthesized by anionic ring‐opening copolymerization of maleic anhydride (MA) and taurine. The structures were characterized by elemental analysis, Fourier transform infrared spectroscopy, nuclear magnetic resonance ( 1 H NMR) and mass spectroscopy. The weight‐average molecular weight ( M w ) of the copolymers was tested using multi‐angle laser light scattering instrument. The biodegradability of the copolymers was judged by the shaking table test method. The possibility of the copolymers to be a detergent builder was assessed in terms of the calcium sequestration capacity which was evaluated in accordance with the China National Standard method (GB/T 21884‐2008) and dispersive power test. The results showed that the copolymers were biodegradable, and possessed a high calcium sequestration capacity and a good dispersancy, which were environment‐friendly detergent builders.
