研究了水溶液中带有负电荷的磺化聚丙烯酰胺与三乙烯四胺之间的相互作用,考察了三乙烯四胺的引入对磺化聚丙烯酰胺黏度及流变学性质的影响.研究发现,三乙烯四胺的加入可以有效地提高磺化聚丙烯酰胺的黏度、抗剪切性及剪切回复性等性能,为进一步研究其在驱油中的应用提供了理论基础.
The water-soluble negatively charged polyacrylamide was prepared by free radical copolymerization method. The interaction between negatively charged sulfonated polyacrylamide and triethylenetetraamine was investigated in aqueous solution and mineralized water. The results indicated that the addition of triethylenetetraamine can efficiently influence the viscosity and theological properties of sulfonated polyacrylamide, which provides the theoretical basis for the further application in oil displacement.
