【摘要】 合成了马来酸酐—丙烯酸甲酯—丙烯酰胺三元共聚物阻垢分散剂，并对其阻垢性能与丙烯酸—丙烯酸甲酯—丙烯酰胺共聚物比较，发现它对循环水温度、硬度及ｐＨ值的适用范围比丙烯酸—丙烯酸甲酯—丙烯酰胺更广，可广泛用作工业循环水特别是高温、高硬度、高ｐＨ值等水质的阻垢分散剂更多还原

【Abstract】 The maleic anhydride methyl acrylate acrylamide copolymer used as antiscaling and dispersing agent was synthesized and its antiscaling property was compared with AA-MA-AM copolymer. It was discovered that the ranges suitable for the recirculating water temperature, hardness and pH value of this copolymer was wider than that of AA-MA-AM. So MAH-MA-AM could be widely used in industrial recirculating water as antiscalant,especially in the water quality with high temperature,high hardness,high pH value.更多还原
