摘　　要：采用MgCl2/AlCl3复合载体制备了乙烯聚合用钒系催化剂FVC-01,以正己烷为分散剂,三异丁基铝为助催化剂,H2为相对分子质量调节剂,在淤浆工艺中研究了FVC-01催化剂催化乙烯与1-丁烯、乙烯与1-己烯的共聚性能。结果表明:FVC-01催化剂具有较好的共聚性能,可采用1-丁烯为共聚单体在单反应器内制备宽相对分子质量分布的高密度聚乙烯。A vanadium-based catalyst FVC-01 for ethylene polymerization was prepared on the MgCl2/AlCl3 composite support.The copolymerization of ethylene/1-butene and ethylene/1-hexene over FVC-01 catalyst were studied in slurry process with hexane as dispersant,triisobutyl aluminum as cocatalyst and H2 as relative molecular mass regulator.The results show that FVC-01 catalyst performs excellently in copolymerization.1-Butene can be used as comonomer to prepare polyethylene with wide relative molecular weight distribution in a single reactor.
