| Abstract: | An alternative route was investigated to prepare linear lower density polyethylene with a single monomer,ethylene,and a dual functional catalytic system for ethylene polymerization in situ using Ti(O n Bu) 4/AlEt 3 as dimerization catalyst and supported metallocene as its copolymerization catalyst.The two catalysts were well matched in a single reactor and the short branched polyethylene made from this catalytic system had the characteristics of low melting point,low density,high activity and proper\|granule morphology of polyethylene. |
