摘　　要：在1L的搅拌釜式反应器中,以α-十二烯为原料,主催化剂为负载型TiCl4/MgCl2,助催化剂为三异丁基铝(齐格勒-纳塔催化剂),外给电子体为DDS(二苯基二甲氧基硅烷),采用本体聚合法,探索了一种连续生产油溶性减阻剂的方法。考察了在该工艺条件下,催化剂的用量及其配比、反应温度和反应时间对聚合物性能的影响,利用室内环道评价装置测定了聚合物的减阻率。研究结果表明,该方法能连续稳定的生产减阻率达到40%左右的减阻剂产品,满足工业生产的要求。With TiCl4/MgCl2 as catalyst,Al（i-Bu）3 as cocatalyst and DDS as external donor,oil soluble drag reducer was continuously synthesized by bulk polymerization in 1L atmospheric and impeller reactor.Effects of catalyst dosage,reaction temperature and reaction time on DRA＇s drag reduction efficiency were studied.Drag reduction efficiency was measured by drag reducing test in circle conduit.Finally,the optimum conditions for α-olefin bulk polymerization were obtained.The experimental results show that drag reducing efficiency of 41.6% can be achieved which meets the request of industry.
