摘　　要：以丙烯酸(AA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)为原料,合成了二元共聚物AA/AMPS,研究了单体配比和合成条件对聚合物极限黏度的影响,并评定了极限黏度对阻垢性能的影响。研究表明:随着AMPS含量的增加,共聚物极限黏度先增后减;随着引发剂用量、分子量调节剂用量的增加和反应温度的升高,共聚物极限黏度逐渐减小;极限黏度在0.08～0.09 dL/g范围内的二元共聚物AA/AMPS对Ca_3(PO_4)_2和锌盐阻垢效果较好。A copolymer was synthesized from acrylic acid and 2-acrylamide-2-methylpropane sulfonic acid （AMPS）. It was investigated that the monomer ratio and synthesis conditions influenced the copolymer limiting viscosity, and evaluated that the limiting viscosity effected on efficacy of scale inhibitors. The results showed that the limiting viscosity increased firstly and then decreased with raise of the AMPS content, and the limiting viscosity diminished gradually with raise of initiator, molecular weight regulator volume and reaction temperature. When the limiting viscosity is in 0.08-0.09 dL/g, the copolymer has better scale inhibition performance to Ca3（PO4）2 and zinc salt.
