摘要
以水做溶剂,采用自制催化剂合成马来酸酐(MA)-丙烯酸(AA)二元共聚物.研究了单体配比、引发剂用量、聚合反应温度和聚合反应时间对共聚物性能的影响.实验结果表明,该共聚物具有较强的螯合Fe^(3+),Ca^(2+)的能力,而且易于生物降解,是一种新型的环保型螯合分散剂.
Maleic anhydride - acrylic acid copolymers have been prepared, which used the water as the solvent. The influence factors of the properties of copolymers were studied such as the ratio of monomers, the amount of initiator, the reaction temperature , the reaction time. The results show that the copolymers whose capacity of sequesting Fe^3＋ and Ca^2＋ is good, and has good biological degradation property. The copolymers is a new environmental friendly chelating dispersing agent.
