| 摘 要： | 在石油管道运输中应用最广泛的减阻剂是直链共聚烯烃类聚合物,但是其极易因分子链的断裂而使其分子量降低,以至失去减阻功能,即通常所说的剪切降解.本文主要合成一种新型抗剪切减阻剂,并对其合成方法、引发剂对聚合单体转化率的影响、缔合减阻剂减阻率及抗剪切性能的比较等进行了实验研究.研究结果表明:该合成反应温和同时反应过程易控制;其抗剪切降解性能好于直链共聚烯烃类高分子减阻聚合物;聚合物的减阻率随加剂浓度的增加而增加,但呈现上升变缓的趋势.同时随着加剂浓度的增加,剪切后加剂与未剪切加剂减阻率变化曲线呈现出吻合的趋势.

| Abstract: | The linear chain copolymerized alkenes polymer is widely used as a drag reducing agent (DRA) in oil pipeline transportation. However,the molecular weight of the drag reducing agent decreased sharply because of chain fracture,and the decreased effectiveness of drag reducing,known as shear degradation. A new kind of anti-shearing drag reducing agent was synthesized. The synthesis method,effect of initiator on the monomer conversion,drag reducing rate of associating DRA and anti-shearing performance were exami... |
