AM/AA/AMPS/AMQC12AB 四元共聚物的合成及耐温抗盐性研究

摘要

A tetrapolymer was prepared by using raw material of AM,AA,AMPS and AMQC12 AB,with VA-044 as the initiator. The effect of the temperature,the amount of initiator and AMPS,AMQC12 AB a-mount and pH value on the intrinsic viscosity were investigated,and determine the optimal reaction condi-tions. The result showed that the optimum polymerization conditions were as follows:reaction temperature 35 ℃,pH was 7 ~ 9,10% for the weight fraction of AMPS,0. 5% for the weight fraction of initiator,0. 5% for the weight fraction of AMQC12 AB,with a alkalescent reaction system. Polymer tests showed that the tetrapolymer had a good tolerance to high salinity and high temperature.%以 AM、AA、AMPS、AMQC12 AB 为单体，VA-044为引发剂，合成了一种新型耐温抗盐的四元共聚物。考察了温度、体系 pH、引发剂用量、AMPS 含量、AMQC12 AB 含量对共聚物特性黏数的影响，并确定最佳反应条件。结果表明，比较适宜的反应条件为：聚合反应温度35℃，体系 pH 值7~9，引发剂用量为单体含量的0.5%，AMPS 含量为单体总含量的10%，加入 AMQC12 AB 含量为单体总含量的0.5%。聚合物测试表明，该聚合物具有良好的耐温抗盐性能。
