An altemative 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(On-Bu)4/AlEt3 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.
