The development of a new generation of carbon dioxide (CO₂) thickeners is significant for improving carbon dioxide flooding technology. Here, co-polymers based on epoxide heptamethyltrisiloxane and glycidyl phenyl ether are prepared, and their solubility and thickening ability in CO₂ are evaluated. The solubility of the modified polyethers in CO₂ remarkably increases with the modification of heptamethyltrisiloxane and decreases upon introducing phenyl glycidyl ether. With incorporation of 18.4 mol% phenyl groups into the co-polymer, the co-polymer exhibits a highly increased thickening effect, while maintaining high solubility in CO₂. Implications of the present study for the preparation of a highly efficient CO₂ thickener are discussed.

改性聚醚作为高效CO2增稠剂的研究

新一代二氧化碳（CO ₂）增稠剂的开发对于改善二氧化碳驱技术具有重要意义。在此，制备基于环氧基七甲基三硅氧烷和缩水甘油基苯基醚的共聚物，并评价它们在CO ₂中的溶解性和增稠能力。改性的聚醚在CO _2中的溶解度随着七甲基三硅氧烷的改性而显着增加，并且在引入苯基缩水甘油醚时降低。通过将18.4摩尔％的苯基结合到共聚物中，该共聚物表现出高度增加的增稠作用，同时保持了在CO _2中的高溶解度。本研究对制备高效CO _2的意义增稠剂进行了讨论。
