Polyolefins are the most widely used and needed polymers in the world. Their
polymerization process is a topic of great interest among scientists. Not only do polyolefins …

We report three niobium-based initiators for the catalytic ring-opening polymerization (ROP)
of ε-caprolactone, exhibiting good activity and molecular weight control. In particular, we …

Despite the useful selectivity offered by vanadium catalysts for olefin polymerization, their
implementation under practical conditions remains limited by poor productivity and thermal …

Soluble vanadium catalysts are highly coveted for their selectivity in olefin polymerization.
However, their utility is limited by rapid deactivation, especially at scalable temperatures …

Two new dihydrazone ligands (H4L1 and H4L2) have been prepared from Hantzsch
pyridine ester and after characterization by analytical methods, they have been used in the …

Radical increase of antibiotic resistance among microbes has become a serious problem for
clinics all over the world that has led to the need for search of novel types of antimicrobial …

Interaction of [VO (O i Pr) 3] with 6-bis (o-hydroxyaryl) pyridine, 2, 6-{HOC (Ph) 2CH2} 2
(NC5H3), LH2, afforded [VO (O i Pr) L](1) in good yield. The reaction of LNa2, generated in …

In the present work, we report a new method for facile and effective synthesis of poly

A series of vanadium (V) aroylhydrazine‐arylolates is employed in ethylene polymerization
to produce ultra‐high molecular weight polyethylene (UHMWPE), surprisingly extending to …

Bimetallic complexes have attracted much attention due to their excellent catalytic
performances in many fields. Herein six xanthene-bridged bis-salicylaldiminato [ON] …
