摘　　要：以环氧琥珀酸(ESA)、丙烯酸(AA)、烯丙基磺酸钠(SAS)和丙烯酸羟丙酯(HPA)为原料,通过溶液聚合法合成了聚羧酸盐共聚物Poly(ESA-AA-SAS-HPA)。采用FT-IR,1H NMR,TG,DLS对其结构进行了表征。考察了螯合pH、温度及助剂质量分数等因素对Poly(ESA-AA-SAS-HPA)助洗性能的影响。结果表明:与三聚磷酸钠相比,其具有良好的助洗性能,鳌合量为308.7 mg/g、钙分散力为101.5 mg/g。同时,Poly(ESA-AA-SAS-HPA)与十二烷基苯磺酸钠(LAS)有良好的协同作用,可将体系表面张力降至45 mN/m。Poly(ESA-AA-SAS-HPA) was synthesized by solution polymerization from epoxy succinic acid(ESA),acrylic acid(AA),sodium allyl sulfonate(SAS) and hydroxypropyl acrylate(HPA).It was characterized by FT-IR,1H NMR,TG and DLS.The effects of chelating pH,temperature and additive mass fraction on the washing aid performance of Poly(ESA-AA-SAS-HPA) were investigated.The results show that,compared with sodium tripolyphosphate,it has good washing aid performance,with the chelating amount of 308.7 mg/g and the calcium dispersing power of 101.5 mg/g.Poly(ESA-AA-SAS-HPA) has good synergism with sodium dodecylbenzene sulfonate(LAS),which can reduce the surface tension of the system to 45 mN/m.
