依据溶度参数理论预测溶剂和聚合物的相容性,为合成具有更高分子量的减阻聚合物提供理论指导。实验结果表明,使用脂肪烃溶剂（正己烷、正辛烷和环己烷）和芳香烃溶剂（甲苯、苯和氯苯）合成减阻剂黏均分子量的大小顺序与依据溶度参数理论预测不同溶剂合成减阻剂的分子量大小顺序吻合。脂肪烃溶剂是α-烯烃聚合的良溶剂,芳香烃溶剂是α-烯烃聚合的不良溶剂。良溶剂中环己烷是α-烯烃聚合的最佳溶剂,易合成分子量较大的减阻剂。同时,通过室内环道评价装置及XRD和1H-NMR测试手段对聚合产物的结构和性能进行了表征。

In this paper,the compatibility between solvent and polymer is predicted according to solubility parameter theory,and a theoretical guidance is provided for the synthesis of drag reduction agent(DRA) with high molecular weight.The experiment results show the viscosity-average molecular weight size order of DRA synthesized by aliphatic hydrocarbon solvents(n-hexane、n-octane and cyclohexane) and aromatic hydrocarbon solvents(cyclohexane、benzene and chlorobenzene) are in accordance with the molecular weight size order of DRA which was synthesized by different solvents predicted according to solubility parameter theory.Aliphatic hydrocarbon solvents are good solvents for α-olefin polymerization,and aromatic hydrocarbon solvents are poor solvents for α-olefin polymerization.Cyclohexane in good solvents is the best solvent for α-olefin polymerization,and is easy to synthesize DRA with large molecular weight.At the same time,the product structure and properties are characterized by simulative loop evaluation apparatus、XRD and1H-NMR.
