Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand.

Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety.

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.
