一种丙烯酰胺共聚物磷酸盐的合成及性能研究
Synthesis and Properties of an Acrylamide Copolymer Based on Phosphate
摘要
Abstract
An acrylamide copolymer was synthesized using acrylamide(AM),acrylic acid(AA),(1-dimethylamino-allyl)-phosphoric acid(DMAAPA)and N-allyl octyl imide(NAOI)as raw materials and NaHSO3-(NH4)2S2O8 as initiator. The optimum synthetic conditions were determined as follows:the appropriate temperature was 45 ◦C ,the initiator was found to be 0.3%,the pH was 7,and m(AM):m(AA):m(DMAAPA):m(DMAAPA)=6.0:4.0:0.015:0.030. The molecular structure of the copolymer was confirmed by IR and 1H NMR,proving that the functional monomers were present in the molecule chain. The retention rate of the copolymer could reach 28.9%(120 ◦C),18.7%(1 000 s−1),and 22.2%(1.2 g/L NaCl)respectively according to the performance evaluation. Up to 10.54%enhanced oil recovery(EOR)could be obtained by core flood testing using 2 000 mg/L copolymer at 65 ◦C .关键词
