Currently, the commonly used oil displacement agent utilizes synthetic polymers, the viscosity of which, however, descends drastically with the increase of temperature and salinity. This research focuses on combining branched macromolecules with linear hydrophobically associating polymer that can improve the anti-shearing performance, temperature tolerance, and salt tolerance of the polymer aqueous solution. We propose a hyperbranched dendritic shape polymer because of unique properties such as relatively low cost, multiple functional groups, a large area of coverage and eco-friendliness compared to linear polymers. This will be one of a novel polymeric surfactant for oil recovery application.

目前，常用的油位移剂利用合成聚合物，但是，粘度随着温度和盐度的升高而急剧下降。这项研究重点是将分支大分子与线性疏水性聚合物相结合，从而可以改善聚合物水溶液的抗剪切性能，温度耐受性和耐盐性。我们提出了一个超支的树突形状聚合物，因为与线性聚合物相比，诸如相对较低的成本，多个官能团，覆盖范围较大和生态友好型等独特特性。这将是用于采油施用的新型聚合物表面活性剂之一。
