摘　　要：以苯乙烯磺酸钠、丙烯酸、丙烯酸甲酯为单体合成了一系列不同分子量的聚合物,探讨了分子量对阻碳酸钙垢、磷酸钙垢,分散氧化铁、锌盐的影响。结果表明:随着分子量的增大,聚合物对碳酸钙和磷酸钙的抑制能力增加,但当聚合物的浓度较大时,分子量对性能的影响减小。A series of copolymers with different molecular weight were synthesized by the monomers of HPAS,AA,HPA. The effect of molecular weight on the scale inhibition of CaCO3 and Ca3 （PO4）2 and dispersion of Fe2O3 and Zinc salts were studied. The results showed that scale inhibition increased with the increases of molecular weight, and the effect of molecular weight on the performance decreased at higher concemtration of polymers.
