Recycling mixed polyolefin plastics is a significant challenge due to the limitations in sorting
and degraded mechanical properties of blends. Nonreactive compatibilization by adding a …

Precise control over product structure is the goal of all chemical synthesis. In the field of
polymer synthesis, the structure of the resultant macromolecule is intimately linked to its …

Polyethylene (PE) and isotactic polypropylene (i PP) constitute nearly two-thirds of the
world's plastic. Despite their similar hydrocarbon makeup, the polymers are immiscible with …

The demand for low-cost high-performance materials has seen polyolefins'1 share of total
polymer production increase from approximately 30% to 60% over the last 30 years (19702 …

A series of isotactic polypropylene (i PP) and polyethylene (PE) diblock, tetrablock, and
hexablock copolymers (BCPs) were synthesized with tunable molecular weights using a …

The opening up of new markets, particularly in the Far East, is expected to increase the
industrial demand for more (and new) plastic materials. In turn, this will drive the need for …

The thermomechanical properties exhibited by synthetic macromolecules can be directly
linked to their tacticity, or the relative stereochemistry of repeat units. The development of …

Bis (pyrrolide− imine) Ti complexes in conjunction with methylalumoxane (MAO) were found
to work as efficient catalysts for the copolymerization of ethylene and norbornene to afford …

Polyolefins are the most widely used plastics accounting for a large fraction of the polymer
waste stream. Although reusing polyolefins seems to be a logical choice, their recycling …

Aiming at higher activities of group IV diamine bis (phenolate) catalysts in olefin
polymerization, ligands containing electron-withdrawing groups have been introduced. The …
