Ultrahigh molecular weight polyethylene (UHMWPE) belongs to an emerging class of high-
performance specialty polymers with a unique set of properties and applications. The field …

This review summarizes the progress of transition metal catalyzed ethylene polymerization
to ultra-high molecular weight polyethylene (UHMWPE), focusing on the catalytic activities of …

A structurally well-defined mesoporous Hf-based metal–organic framework (Hf-NU-1000) is
employed as a well-defined scaffold for a highly electrophilic single-site d0 Zr–benzyl …

Chain entanglements, which reside in the amorphous phase of semicrystalline polymers,
influence many macroscopic properties of polymers. There are different opinions about the …

Polyethylene with a molecular weight greater than a million g/mol, is of increasing
commercial interest because it provides a route to make fibers and films that have …

Several homogeneous postmetallocene complexes are known to produce weakly entangled
ultrahigh-molecular-weight polyethylene (disentangled UHMWPE) under controlled …

Polyethylene's and polypropylenes are most studied polymers by different solid-state NMR
methods. Among various NMR methodologies used, time-domain proton NMR (TD-NMR) …

Disentangled ultrahigh molecular weight polyethylene (dis‐UHMWPE) has excellent
processability but can be achieved under extreme conditions. Herein, we report ethylene …

Chain entanglement was very important for adjusting the processability and mechanical
property of nascent ultrahigh molecular weight polyethylene (UHMWPE). So far, it is still a …

A methodology for estimating the entanglement density in the amorphous phase of
semicrystalline polyolefins was developed. The method is based on the analysis of the …
