Sodium salt of Polyepoxy N-maleoyl-2-aminoethanesulfonic acid is synthesized from maleic an-hydride and taurine via amidate,epoxidation and anion ring-opening copolymerization reaction.The structure is characterized with nuclear magnetic resonance ( 1 H-NMR),Fourier transform infrared spec-troscopy ( FTIR),mass spectroscopy and elemental analysis.By an orthogonal testing method,the opti-mized technological conditions are as follows:95 ℃of the reaction temperature,6 h of the reaction time and 4%of the mass fraction of Ca ( OH) 2.The synthetic copolymer P ( MA-co-taurine) has excellent but controllable detergent properties.The chelation and dispersion are 326.8 mg CaCO3/g and 124.9 mg CaCO3/g respectively.The biodegradability of the copolymers can be demonstrated by shaking table test and the properties have been compared with other detergent builders.
