采用异辛醇(IOOH)萃取合成了VO2Cl.3IOOH配合物,在Et3Al2Cl3的活化下,常压下催化乙烯/1-己烯的共聚合,活性达58.5 kg/(mol V.h),产品中1-己烯含量为1 mol%～13 mol%,以乙烯单元所隔离的孤立的形式而存在,相应聚合物熔点(Tm)为68～116℃,低于纯线性高密度聚乙烯,而储能模量和复合粘度均高于纯线性高密度聚乙烯。钒配合物的结构用元素分析及红外光谱分析(IR)测定,聚合产物结构用差示扫描量热仪(DSC)及核磁共振波谱分析(13CNMR)测定,粘弹性用流变仪测定。
VO2Cl.3IOOH complex was synthesized by isooctanol (IOOH) extraction. The copolymerization of ethylene / 1-hexene with 58.5 kg / (mol Vh) under the activation of Et3Al2Cl3 was carried out at atmospheric pressure. The 1- Hexene content of 1 mol% ~ 13 mol%, isolated in the form of ethylene units exist, the corresponding polymer melting point (Tm) of 68 ~ 116 ℃, lower than the pure linear high density polyethylene, and the energy storage mode Both the amount and the complex viscosity are higher than pure linear HDPE. The structure of the vanadium complex was determined by elemental analysis and infrared spectroscopy (IR). The structure of the polymer product was measured by differential scanning calorimetry (DSC) and nuclear magnetic resonance spectroscopy (13C NMR), and the viscoelasticity was measured by a rheometer.
