An effective method of 1-hexene polymerization in fluorous reaction media has been developed. When using perfluorinated compounds (FCs) as a solvent, the process, catalyzed by highly active titanium-magnesium catalysts modified with 3,3-bis(methoxymethyl)pentane (BMMP) as an electron-donor, proceeds as a precipitation polymerization, and the reaction products represent highly stereo- and regioregular poly(1-hexene)s in the form of microparticles. In freons, polymerization can be carried out at sub-zero temperatures with monomer conversion up to 50% within 1 h and the formation of UHMW poly(1-hexene)s with M_n ∼2·10⁶ Da. The polymers prepared in FCs demonstrate a high drag reducing effect (up to 40% in n-heptane for 0.25 ppm concentration), exceeding the previously described UHMW poly(1-hexene)s. Polymerization products after mixing with rapeseed oil form stable dispersions of ready-to-use drag reducing agents (DRAs) for pipeline oil transportation.

已经开发了一种在氟反应介质中1-己烯聚合的有效方法。当使用全氟化合物（FCs）作为溶剂时，该过程由以3,3-双（甲氧基甲基）戊烷（BMMP）修饰为电子给体的高活性钛-镁催化剂催化，作为沉淀聚合反应进行，并且反应产物以微粒形式代表高度立体和区域规则的聚（1-己烯）。在氟利昂，聚合可在零度以下的温度与单体转化率在1个小时内进行高达50％和UHMW聚（1-己烯）的形成s的中号_ñ〜2·10 ⁶ 道尔顿。在FC中制备的聚合物表现出很高的减阻效果（以n计可达40％-浓度为0.25 ppm的正庚烷），超过了先前描述的UHMW聚（1-己烯）。与菜籽油混合后的聚合产物可形成稳定的，即用型减阻剂（DRA）分散体，用于输送管道油。
