The Cover Feature shows an artistic interpretation of a supported polymerization catalyst particle that is fragmenting during ethylene polymerization. In their Research Article, F. Meirer, B. M. Weckhuysen and co-workers used high resolution X-ray electron microscopy to elucidate the origins sectioning fragmentation mechanism in two different silica-supported olefin catalysts at single level. o...

Terpolymers are used to generate bio-decomposable self-assemblies. PEG-PVL-PGMA terpolymers synthesized via a combination of organocatalyzed living radical polymerization (RCMP) with polymerization-induced self-assembly (PISA), generating vesicle, multicompartment micelle (MCM), and core-compartmentalized worm (CCW), where PEG, PVL, PGMA poly(ethylene glycol) monomethyl ether, poly(?-valerolact...

Covalent organic framework (COF) particles with hydroxy groups and well-defined micropores have been synthesized used as novel carriers to load a metallocene catalyst—Cp2ZrCl2. The resulting supported catalyst, which had high specific surface area, demonstrated higher catalytic activity, better thermal tolerance, unique nanoconfinment effect during ethylene polymerization, producing polyethylen...

UV free-radical polymerization techniques are often used to synthesize hydrogels for controlled release applications. Numerous techniques exist for immobilizing drugs or solutes in the gel. This work focuses on the entrapment of solute in a hydrogel by conducting a photopolymerization in the presence of the monomer and the solute. A kinetic gelation model has been developed to examine the effec...
