摘　　要：采用本体聚合，以球形Ziegler-Natta负载型催化剂为主催化剂，三异丁基铝为助催化剂，二苯基二甲氧基硅烷为外给电子体，制备了长链α-烯烃共聚物，考察了共聚单体混合比及反应条件对共聚合的影响，并进行了放大实验，测试了共聚物的减阻性能。结果表明：在n（A1）／n（Ti）为100，n（Si）／n（Ti）为5，1-十二烯与1-辛烯质量比为1：1，反应温度0～2℃，反应时间15天的条件下，共聚物的特性黏数和共聚单体转化率较高。制备的超高相对分子质量长链0α-烯烃共聚物对石油输送具有良好的减阻效果．增输率可达20．16％。A series of long chain α-olefin copolymers were prepared via bulk polymerization with a spherical Ziegler-Natta supported catalyst as main catalyst, triisobutyl aluminum as cocatalyst and diphenyl dimethoxy silane as external electron donor. The effects of the comonomer mixing ratio and reaction conditions on the copolymerization were studied, the scale-up experiment was carried out, and the drag reduction performance was tested. The results show that the intrinsic viscosity of the copolymer and conversion of the comonomer are comparatively high when the molar ratio of A1 to Ti and Si to Ti are 100 and 5, respectively, mass ratio of 1-dodecene to 1-octene is 1 ： 1, reaction temperature is 0-2 ℃ and reaction time is 15 days. The long chain high relative molecular mass α-olefin copolymer so prepared has excellent effect of drag reduction on oil transportation. The increase rate in oil transportation can reach 20.16%.
