运用分子设计的方法论,从理论与实践上对主链聚合物的组成、分子量、结构与聚集态,枝链聚合物的结构、与主链聚合物的相容性,不同条件下的反应能力,枝链长度、枝链度及其位置分布以及接枝化合物结构对溶解能力、增粘性能。流变与异常粘—温依赖关系、表面性能等影响进行了探讨。在此基础上论证了以木薯淀粉为主链聚合物、以芳环及顺酐、甲基丙烯酸为基本单元的共聚物为枝链聚合物进行接枝共聚,以制备耐温、抗剪切降解、增稠能力与表面活性作用良好水溶性的新型高聚物驱油用材料的可能性与现实性。并为进一步的分子设计研究打下了基础。
Using the methodology of molecular design, the composition, molecular weight, structure and aggregation of the main chain polymer, the structure of the branched chain polymer, the compatibility with the main chain polymer, the reaction ability under different conditions, The length of the branch chain, the degree of branching and its position distribution and the grafting structure of the compound on the dissolving ability and the thickening property. Rheological and abnormal viscosity - temperature dependence, surface properties and other effects were discussed. On the basis of this, it is demonstrated that the tapioca starch as the backbone polymer, the aromatic ring and the maleic anhydride, methacrylic acid as the basic unit of the copolymer as a branched chain graft copolymer to prepare for temperature resistance, shear resistance to degradation , Thickening ability and surface activity of a good water-soluble polymer flooding a new possibility and feasibility of material. And laid the foundation for further molecular design and research.
