三元丙烯酰胺共聚物驱油剂 PVAA 的合成及性能测试

The Study of Synthesis and Properties for Terpolymer Flooding Agent—PVAA

由乙烯基吡咯烷酮（ＮＶＰ）与丙烯酰胺（ＡＭ）、丙烯酸（ＡＡ）通过反相乳液聚合法合成了三元共聚物驱油剂ＰＶＡＡ，用正交试验法确定了聚合体系主要成分的配比，并测试了共聚物水溶液的耐盐性及热稳定性．结果表明，ＰＶＡＡ的耐盐性、耐热性均好于部分水解聚丙烯酰胺．

A type of polyacrylamide flooding agent, modified by vinyl pyrrolidine, was prepared by inverse emulsion polymerization. The composition of polymerization system was determined by orthogonal test. The resistance to salt and thermal stability of the modified copolymer was also measured. The results show that the abovementioned properties of the modified copolymer are superior to those of partially hydrolyzed polyacrylamide.
