Cyclic polymers present a topology that differ significantly from their linear counterparts due
to their circular structure and therefore, the lack of chain ends. These simple characteristics …

Cyclic polymers have long been reported in the literature, but their development has often
been stunted by synthetic difficulties such as the presence of linear contaminants. Research …

Zn (HMDS) 2 as a simple, biocompatible, efficient, and supporting ligand-free metal catalyst
has been achieved for polyesters synthesis and degradation. The catalyst not only has a …

We report here on the ring‐opening polymerization (ROP) of racemic β‐thiobutyrolactone
(rac‐TBL), as the first chemical synthesis of poly (3‐thiobutyrolactone)(P3TB), the thioester …

The depolymerization of plastic waste to valuable chemicals (waste‐to‐chemicals) can be a
useful implement for a resource‐efficient economy. In this regard, the selective …

Isoenriched poly-3-hydroxybutyrate (P3HB) is a biodegradable material with properties
similar to isotactic polypropylene, yet efficient routes to this material are lacking after 50+ …

A series of homonuclear rare-earth (RE) metal complexes (1 Y, 2 Yb, 3 Nd, and 4 La) and
heteronuclear RE–Zn complexes (1 Y–Zn, 3 Nd–Zn, and 5 Sm–Zn) stabilized by …

The in situ generation of metal-alkoxide complexes is a common initiation method in cyclic
ester ring-opening polymerization. However, this method is often a “black box”, where the …

Cyclic polymers exhibit physical properties that are distinct from their linear analogues.
However, syntheses of cyclic polymers from macrocyclic structures with chemical recycling …

The efficient formation of cyclic polyesters from the ring‐opening polymerization of lactide, ϵ‐
caprolactone, and β‐butyrolactone catalyzed by a 1, 4‐dithiabutanedyl‐2, 2′‐bis (4, 6 …
