摘　　要：以络合型TiCl3催化剂、N型Ziegler-Natta催化剂和[O,O,N,N]茂金属为主催化剂,采用本体聚合方法,制备了单峰和双峰聚α-烯烃油品减阻剂,考察了催化剂的种类与用量对聚α-烯烃分子质量、分子质量分布及减阻剂性能的影响。结果表明:3种催化剂中,[O,O,N,N]茂金属催化剂的催化效率最高,制备的聚α-烯烃分子质量、分子质量分布及减阻性能最优;使用双金属络合型TiCl3和[O,O,N,N]及N型Z-N和[O,O,N,N]制备的双峰聚α-烯烃减阻剂的起效速度和减阻效果均优于单峰聚α-烯烃减阻剂。：DRA with single-peak and double-peak poly a-olefine for oil products are prepared through bulk polymerization by using bimetallic complex TIC13 catalyzer, N type Ziegler-Natta catalyzer and [O, O, N, N] metallocene as major catalyzers to determine the impacts of catalyzer types and volumes on molecular mass, distribution of molecular mass of poly a-olefine products and performances of DRA. Research results show that [O, O, N, N] metallocene catalyzer has the highest efficiency in all of the three catalyzers. In addition, produced poly a-olefine products have the most favorable molecular mass, molecular mass distribution and drag reducing performances. Efficiency and drag reducing performances of double-peak poly a-olefine DRA produced by using bimetallic complex TiC13 and [O, O, N, N] and N type Z-N and [O, O, N, N] are all superior than that of single-peak poly a-olefine DRA. （6 Fiaures. 19 References）
