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 …

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 …

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 …

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

Abstract Since 1963, when Karl Ziegler and Giulio Natta were jointly awarded the Nobel
Prize for their discoveries of the catalytic polymerization of olefins with Ti-chlorides and Al …

A series of new alkoxy‐amino‐bis (phenols)(H2L 1–6) has been synthesized by Mannich
condensations of substituted phenols, formaldehyde, and amino ethers or diamines. The …

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 …

An isomerically pure, C 2-symmetric Ni (II) complex was synthesized and found to be living
for propylene polymerization. The regioselectivity of the catalyst varied greatly with reaction …

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 …

The mechanism of the ring-opening polymerization of rac-β-butyrolactone using yttrium
complexes supported by dianionic aminoalkoxybis (phenolate) ligands as initiators has …
