“…Star-shaped poly(hydroxybutyrate)s from bio-based polyol cores via zinc catalyzed ROP of β-BL were reported. 87 The structures were constructed by a core-first approach, in which bio-based multifunctional alcohols were used as the initiator for β-BL ROP. The efficient initiation by the three-, four-, and multi-armed cores was confirmed by NMR analysis.…”

Ring‐opening polymerization (ROP) is a versatile synthetic method used to produce polymers from cyclic monomers, particularly oxacyclic monomers such as lactones and cyclic ethers. Oxacyclic monomers polymerize with anionic or cationic initiators. For selected monomers, such as glycidol, β‐butyrolactone and higher lactones, methods, and mechanisms of polymerization are presented, the understanding of which has allowed control of these processes. The use of appropriate polymerization techniques and methods, as well as conducting the copolymerization, mainly block copolymerization, makes it possible to control the architecture, molar mass, and end groups of the resulting polymers. These parameters determine the properties of macromolecules, such as solubility, ability to aggregate in aqueous solutions, thermoresponsiveness, and degradability. By carefully selecting monomers, catalysts, and polymerization conditions, ROP strategies can be tailored to produce polymers with precise molecular structures and desired properties for a wide range of applications. This review mainly focuses on precisely controlled syntheses that lead to well‐defined macromolecules consisting mostly of polyether and/or polyester chains.

“…This approach utilizes initiators, monomers such as β-lactones and cyclic esters, and metal catalysts for polymerization to occur . Diverse homopolymers and copolymers may be produced using a clever combination of monomers and catalysts. , A recent study reported the possibility of using nonmetallic catalysts in ring-opening polymerization of β-butyrolactone (BBL). The authors found the versatility of a series of bifunctional organoboron catalysts in terms of reactivity and selectivity during ROP.…”

The runaway production and consumption of oilbased plastics are key drivers of global warming and the increased carbon footprint. Besides, most of this plastic debris ends up in the oceans and constitutes about 80% of all marine debris. This pollution problem calls for a seismic shift to eco-friendly plastics and marine biodegradable ones. Unlike other biobased polymers, polyhydroxyalkanoates (PHAs) take pride in their degradation in soil and marine environments. This intriguing marine biodegradation property of PHAs sets it apart as the best choice to curb microplastics, particularly in marine ecosystems. PHAs have also grown in popularity due to other quintessential properties such as biocompatibility, structural variety, and similarity to conventional plastics in terms of physical properties. PHAs are being widely researched for various applications, including packaging, medical, energy, and agriculture. This perspective comprehensively focuses on the state-of-art production and applications of PHA plastics as well as the practical recycling strategies for postconsumer PHAs. The innovative "next generation industrial biotechnology" (NGIB) is well covered in this perspective. Moreover, the nexus between end-of-life strategies and life cycle assessment (LCA) of PHAs waste is elucidated to understand its impact on the environment thoroughly.

“…Besides tin compounds, other catalysts such as calcium hydride, 16 potassium hexamethyldisilazide 17 and bismuth( iii ) acetate 18 were also employed. Further, more biologically friendly aluminium salen and salan, 19,20 zinc amino-, thio-phenolate or zinc amido-oxazolinate 21 and diiminate complex 22 extended the range of metal mediators for the synthesis of star-shaped polyesters. In addition, Lewis acid catalysts based on tin and aluminum allowed control of polymerization and provided polymer stars with variable tactics.…”
