Disclosed herein are processes for producing blends of recycled polymeric material and virgin polyethylene. Post-consumer recycled plastic (PCR) can vary widely with respect to composition which includes mixtures of variable amounts of different polar and non-polar polymers such as polyethylene, polypropylene, ethylene vinyl alcohol, and polyamide. Mixing PCR and virgin polyethylene is inconsistent, partially due to variability, and frequently results in a final product with poor mechanical and optical properties. The process described herein of adding PCR to a solution polymerization process provides another option for blending PCR and virgin polyethylene that offers an ability to exert greater control on the properties of the final product, independent of the composition of the PCR.

Processes for producing polyethylene containing recycled non-polar polymeric material

Oxidative dehydrogenation catalysts for converting lower paraffins to alkenes such as ethane to ethylene when prepared as an agglomeration, for example extruded with supports comprising slurries of NbO.

Agglomerated ODH catalyst

Oxidative dehydrogenation catalysts for converting lower paraffins to alkenes such as ethane to ethylene when prepared as an agglomeration, for example extruded with supports chosen from slurries of TiO, ZrOAlO, AlO(OH) and mixtures thereof have a lower temperature at which 25% conversion is obtained.

A dual reactor solution polymerization process gives high density polyethylene compositions containing a first ethylene copolymer and a second ethylene copolymer and which have high dimensional stability, excellent processability as well as good organoleptic properties and reasonable stress cracking resistance. The polyethylene compositions are suitable for compression molding or injection molding applications and are useful, for example, in the manufacture of caps and closures for bottles, and for example, in bottles containing non-pressurized liquids.
