Heterogeneous Ziegler-Natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. In our previous study, it was reported that MgCl2-supported titanocenecatalysts can generate both Ziegler-Natta-type and metallocene-type active sites according to the type of activators.The dual active site nature of the supported titanocene catalysts was furt...

Poly(lactic acid) (PLA) is one of the best candidates as a sustainable plastic material for circular economy, being biodegradable, bio-based, recyclable, and displaying good thermal mechanical properties. The industrial production PLA mainly based on ring opening polymerization (ROP) l-lactide (l-LA) promoted by tin(II) 2-ethylhexanoate [Sn(Oct)2] in continuous solvent-free process operating at...

Cyanobacteria are recognized producers of a wide array of toxic or otherwise bioactive secondary metabolites. The present study utilized the zebrafish (Danio rerio) embryo as an aquatic animal model of vertebrate development to identify, purify and characterize lipophilic inhibitors of development (i.e., developmental toxins) from an isolate of the freshwater cyanobacterial species, Aphanizomen...

Abstract Tetranuclear Ga(III) complexes L 1–3 2 Ga 4 ( t ‐Bu) 8 1 – 3 are synthesized and characterized (elemental analysis, IR, H, 13 C, DOSY NMR spectroscopy, XRD) their activity in the ring‐opening polymerization (ROP) of lactide (LA) ϵ‐caprolactone ϵ ‐CL) is reported. Complex most active homopolymerization catalyst presence benzyl alcohol (BnOH), yielding isotactic‐enriched polylactides (PL...

Since the maximum foaming temperature window is only about 4 °C for supercritical CO₂ (scCO₂) foaming of pristine polypropylene, it is important to raise the melt strength of polypropylene in order to more easily achieve scCO₂ foaming. In this work, radiation cross-linked isotactic polypropylene, assisted by the addition of a polyfunctional monomer (triallylisocyanurate, TAIC), was employed in ...
