【摘要】 以水为溶剂合成了马来酐丙烯酸共聚物钠盐（简称马丙共聚物钠盐）对其螯合性能、分散性能及复配成洗衣粉的去污效果进行了研究。结果表明：马丙共聚物钠盐具有良好的螯合能力和分散能力，与４Ａ沸石复配后得到的洗衣粉去污指数高于以ＳＴＰＰ为助剂的标准粉更多还原

【Abstract】 The sodium salt of maleic anhydride acrylic acid copolymer (MA Co AA)is synthesized in the water.Its chelate properties,dispersive properties and detergent effect of built powder detergent were studied.The result show that the sodium of MA Co AA have excellent chelate ability and dispersibility,the detergency of powder detergent using the sodium salt of MA Co AA and 4A zeolite as complex builder were more than that of the standard powder detergent with STPP builder.更多还原
