Abstract:

The scale inhibitor, aqueous soluble terpolymer PMVA has been synthesized by using maleic anhydride(MA), vinyl acetate(VA) and acrylic acid(AA) as monomers, ammonium persulphate as initiator and iso-propyl alcohol as molecular weight regulator. Through the research on the effects of the synthetic conditions on scale inhibition capacity and biodegradation of polymers, the optimal technological conditions have been obtained. The capacities of the final product PMVA are tested in many ways, and the results show that PMVA has excellent scale inhibiting and dispersing capacities for CaCO₃ and CaSO₄, strong stabilizing capacity for zinc, and good biodegradability.

Key words: terpolymer, preparation, scale inhibitors

摘要：

以马来酸酐(MA)、乙酸乙烯酯(VA)和丙烯酸(AA)为单体,过硫酸铵为引发剂,异丙醇为分子质量调节剂,合成了水溶性马来酸酐三元共聚物阻垢剂PMVA。通过研究各合成条件对聚合物阻垢性能和生物降解性能的影响,得到最佳工艺条件。并对最终产品进行多方面性能测试,结果表明: PMVA具有优良的碳酸钙、硫酸钙阻垢分散性能,较强的稳锌性能和良好的可生物降解性能。
