  • CO-SUPPORTED CATALYSTS FOR THE TANDEM TRIMERIZATION AND POLYMERIZATION OF ETHYLENE TO PRODUCE LINEAR LOW DENSITY POLYETHYLENE
    Publication number: 20170210834
    Abstract: Linear low density polyethylene (LLDPE) is produced from an ethylene-only feed over a tandem catalyst system consisting of a phenoxy-imine titanium trimerization catalyst and a silylene-linked cyclopentadienyl/amido titanium polymerization catalyst co-supported on the same methylaluminoxane/silica particles. The level of 1-hexene incorporation in the LLDPE can be controlled by varying the ethylene pressure. Tandem, co-silica-supported ethylene trimerization and ethylene/1-hexene copolymerization catalysts produce linear low density polyethylene (LLDPE) from an ethylene-only feedstock. The percentage 1-hexene incorporation in the LLDPE may be varied by adjusting the amounts of the two catalysts on the silica support.
