Cobalt–Oxygen Bond Homolysis in the Bench‐Stable (Salen*)Cobalt(III) Acetate Complex: Insight into the Organometallic Mediated Radical Polymerization of Diverse Monomers

Macromolecular Chemistry and Physics, EarlyView.
The air‐stable [(Salen*)Co(OAc)] complex initiates the radical polymerization of vinyl monomers via Co–O bond homolysis, distinguishing it from classical air‐sensitive cobalt complexes relying on Co‐C bond cleavage. Accordingly, MMA polymerization proceeds via catalytic chain‐transfer while MA undergoes controlled OMRP involving two distinct initiation

Next Generation Reusable Solid Support for Fmoc‐Based Solid‐Phase Synthesis

Macromolecular Chemistry and Physics, EarlyView.
This study presents an efficient on‐resin cyclic acetal formation strategy for resin reuse in Fmoc‐based SPS. The new single‐step approach avoids on‐resin hydrolysis and achieves near‐quantitative yields with fewer resources and reduced reaction times.

Sustainable Shell Formulations as Alternative to the Conventional Soft Gelatin Capsules in Pharmaceutical and Nutraceutical Applications. A Review.

Macromolecular Materials and Engineering, EarlyView.
In soft capsules (SCs), four crucial factors can modify the properties of the shell: the shell formulation, its interaction with the fill material, the SC production and its storage conditions. Gelatin is the most used gelling agent for SCs nowadays, but they have some drawbacks which can be solved including other alternative polymers in the shell ...

Melt Processing of Cellulose Acetate for Controlled Release Applications – A Review

Macromolecular Materials and Engineering, EarlyView.
This review presents recent developments in the melt‐processing of cellulose acetate (CA). Factors affecting the processability, biodegradability, and mechanical performance of CA are also summarized. Plasticizers, bio‐based polymers (PLA, PBAT & PHBV), and clay nanoparticles are also examined toward enhancing the melt processability and mechanical ...
