摘　　要：采用本体聚合法,以TiCl4为主催化剂、Al(i-Bu)3为助催化剂合成α-己烯/α-十二烯减阻剂。用IR,1HNMR,TG等手段对聚合物结构进行表征,考察了主催化剂用量、助催化剂用量对减阻剂特性黏度的影响,并采用室内环道评价装置对减阻率进行测试。结果表明:在主催化剂用量为0.09 g、助催化剂用量为0.12 mL、α-十二烯与α-己烯体积比为2∶1(α-十二烯与α-己烯总体积为40 mL)、反应时间为48 h、反应温度为-5℃的条件下,聚合物特性黏度为11.21 dL/g;当减阻剂在柴油中质量分数为10μg/g时,减阻率达到50.81%。A drag reducing agent （DRA）,α-hexylene/α-dodecene,was synthesized by bulk polymerization using TiC14/Al （i-Bu）3 as catalyst. The obtained polymer was characterized by means of IR,1HNMR and TG. The effect of main catalyst and co-catalyst dosages on the intrinsic viscosity of the synthesized DRA was investigated and its drag reducing efficiency was tested with a loop evaluation device. Results showed that under the optimum conditions of a main catalyst dosage of 0.09 g,a co-catalyst dosage of 0.12 mL,α-dodecene/α-hexylene volume ratio of 2 （α- total volume of 40 mL） ,a reaction temperature of --5℃ and a reaction time of 48 h,the intrinsic viscosity of the synthesized DRA was 11.21 dL/g; by adding said DRA to diesel fuel at a dosage of 10 μg/g,its drag reducing rate reached 50.81%.
