加料方式对磺化苯乙烯/丙烯酸共聚物阻垢性能的影响

Scale inhibition test of sulfonated copolymers of styrene and acrylic acid (St/AA)with different feed methods

利用不同的加料方法和不同加料顺序合成了聚苯乙烯/丙稀酸共聚物,并在吡啶中以发烟硫酸为磺化剂进行磺化制得磺化苯乙烯/丙烯酸(St/AA)共聚物。测定St/AA共聚物阻垢率的实验结果表明,部分滴加2种单体的混合物所得聚合物阻垢性能最好,最大阻垢率达98.5%。

The sulfonated copolymers of styrene and acrylic acid(St/AA) were synthesized by using different feed methods and different feed sequences.It's scale inhibition performance was tested,the results obtained show that the method of partadding mixture of acrylic acid and styrene is optimum method and its scale inhibition ratio reached to 98.5%.
