A tobacco smoking device comprises a porous mass of active particles adapted to enhance a tobacco smoke flowing over said active particles and binder particles. The active particles comprises about 1-99% weight of the porous mass, and the binder particles comprises about 1-99% weight of said porous mass. The active particles and said binder particles are bound together at randomly distributed points throughout the porous mass. The active particles have a greater particle size than the binder particles.

In a process for producing high molecular weight polyethylene, ethylene is contacted with a slurry of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand under polymerization conditions comprising a temperature of about 20&#xb0; C. to less than 90&#xb0; C. and a pressure of about 4 bar to about 40 bar.

Process for producing high molecular weight polyethylene

In a process for producing polyethylene having a molecular weight of at least 3&#xd7;105 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition in at least one hydrocarbon. The catalyst composition comprises a Group 4 metal complex of a phenolate ether ligand and the slurry includes from about 5 to less than 40 ppm per liter of a compound effective to increase the conductivity of said at least one hydrocarbon.

In a process for producing an elongated polyethylene component, such as a fiber or membrane, polyethylene powder having a molecular weight of at least 3&#xd7;10g/mol as determined by ASTM 4020 is dissolved in a solvent to produce an extrudable solution. The solution is then extruded through a die to form an elongated component and at least part of said solvent is removed from the elongated component. The polyethylene powder used in the process is produced by polymerizing ethylene in the presence of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand.

High molecular weight polyethylene fibers and membranes, their production and use

In a process for producing polyethylene having a molecular weight of at least 3&#xd7;10g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand, wherein the slurry further includes a scavenger comprising an alkyl magnesium compound.
