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。 The monomeric and bimodal poly-α-olefin oil drag reducing agents were prepared by bulk polymerization using complex TiCl3 catalyst, N-type Ziegler-Natta catalyst and [O, O, N, N] metallocene as main catalysts The effects of the type and amount of catalyst on the molecular weight, molecular mass distribution and drag reducer properties of poly-α-olefins were investigated. The results showed that the catalytic efficiency of the [O, O, N, N] metallocene catalyst was the highest among the three catalysts, and the molecular weight distribution, molecular weight distribution and drag reduction performance of the prepared polyalphaolefins were the best. The bimetallic complex The bimodal polyalphaolefin drag reducing agent prepared by TiCl3, [O, O, N, N] and N-type ZN and [O, O, N, N] α-olefin drag reducing agent.
