摘要
用溶液聚合法,以轻质油为溶剂,一氯二乙基铝/四氯化钛为催化体系,C10~14α-烯烃为单体,合成了一种长侧链聚烯烃类油溶性减阻剂。该聚合物未经脱溶剂处理,减阻率高达45%(添加质量浓度为0.01kg/m3),超过了本体聚合法得到的聚合物(减阻率为40.1%)。热重分析表明,聚合物在380℃开始分解,唯一的热失重阶段大约为380℃~450℃。聚合物溶胀前后XRD测试结果显示:溶胀前聚合物结构规整性较差,溶胀后使主链和侧链部分展开,规整性提高。最后研究了聚合物溶液的抗剪切稳定性。
A class of oil-soluble drag reduction polyolefin with long side chains was synthesized with light oil as solvent,TiCl_4/Al(Et)_2Cl as catalyst system and C_(10)～C_(14)α-olefins as monomers by solvent polymerization.A 45% of the drag reducing efficiency can be achieved under the conditions of not coping with the polymer(adding mass concentration of 0.01 kg/m^3),which exceeds that of polymer by bulk polymerization(40.1% of DR).TGA shows the sample has an initial decomposition temperature of 380℃,and has only a weight loss stage of 350～450℃.XRD spectra show that structure of the polymer before solving is out of order and after the polymer is solved,a part of main chains and side chains are spread and the orderliness is improved.Finally,the shear stability of polymer solution was studied.
