AA/AMPS/DMDAAC三元共聚物阻垢分散剂的合成与性能研究

摘要

With acrylic acid(AA),2-acryamido-2-methylpropane sulfate acid(AMPS),diallyl dimethyl ammonium chloride(DMDAAC) as the monomer,sodium bisulfite,ammonium persulfate as initiator,using aqueous solution polymerization,we synthesized AA/AMPS/DMDAAC ternary copolymer scale inhibition and dispersion agent. The research results show that the total monomer mass fraction in the solution is 30%,and the initiator mass fraction is 8%(contents of monomer). The experiment is conducted in the weak alkaline environment and reaction under 90℃for 5 h,then the copolymer has good scale inhibition dispersing performance.%以丙烯酸（AA）、2-丙烯酰胺-2-甲基丙磺酸（AMPS）、二甲基二烯丙基氯化胺（DMDAAC）等为单体，亚硫酸氢钠-过硫酸铵为引发剂，采用水溶液聚合法，合成AA/AMPS/DMDAAC三元共聚物阻垢分散剂。研究结果表明，溶液中总单体质量分数为30％，引发剂质量分数为8％（占单体含量），实验在弱碱性环境中进行，90℃下反应5 h得到的共聚物有良好的阻垢分散性能。
