Summary: Designing biocompatible polymeric biomaterials with programmable life cycles is crucial in reducing the negative environmental impact of plastic waste disposal. In this study, deep eutectic solvent monomers (DESm) consisting of l-lactide and various lactones were formulated to obtain polyesters at low temperatures using organocatalysts and solventless conditions. The expansion of DESm allows for the design of polyesters with tailored molecular weights and crystallinity, contributing to programmable degradability. The ROP of DESm under low temperature and solventless conditions holds promise for the sustainable preparation of biodegradable polymers for biomedical applications.

Summary: Boron-functionalized polymers have wide applications in opto-electronics, biology, and medicine. However, methods to produce boron-functionalized and degradable polyesters are rare. This study presents a controlled ring-opening copolymerization method to produce boron-functionalized polyesters. The resulting polymers have adjustable structures, molecular weights, and boron functionalities. The boronic ester-functionalized polymers are amorphous and have high glass transition temperatures and good thermal stability. The utility of this method is demonstrated by synthesizing fluorescent spherical nanoparticles. This versatile technology provides a platform for future explorations of degradable and functional polymers.

Summary: Visible light-regulated organocatalytic polymerization has received significant attention in recent years due to its mild, metal-free reaction conditions and the ability to mediate polymerization with spatial and temporal control. In this study, hydroxybenzophenones (BPOHs) were successfully identified as an effective class of photoacid catalysts for the ring-opening polymerization of lactones, resulting in biodegradable polyester products with predictable molecular mass and low dispersity under visible light irradiation.

Summary: The study describes an effective unimolecular anion-binding organocatalysis for ring-opening polymerization of O-carboxyanhydrides (OCAs), achieving the synthesis of highly isotactic poly(phenyllactic acid) (Ph-PLA) through a dynamic cooperative anion-binding mechanism. This approach addresses the challenge of synthesizing high molecular weight stereoregular polyesters by facilitating efficient chain propagation and maintaining high selectivity for OCA ring-opening over side reactions.

Summary: The research showed that 2,2'-dihydroxybiphenyl is the most successful cocatalyst for bismuth subsalicylate in ring-opening polymerization of l-lactide, and optimization of reaction time and temperature is crucial for achieving high weight average molecular weights. Additionally, some unusual transesterification reactions were discovered, and triphenylphosphine was found to be an effective catalyst poison.

Summary: Despite recent advancements in mechanochemical polymerization, understanding the unique mechanochemical reactivity during the ball milling polymerization process still requires extensive investigations. Here, the authors use solid-state anionic ring-opening polymerization to synthesize polyethers from various functional epoxide monomers. The critical parameters of the monomers are investigated to elucidate the unique reactivity of ball milling polymerization. The controllable syntheses of the desired polyethers are characterized via NMR, GPC, and MALDI-ToF analyses. Interestingly, bulky monomers exhibit faster conversions in the solid-state in clear contrast to that observed for solution polymerization. Particularly, a close linear correlation is observed between the conversion of the ball milling polymerization and melting point of the functional epoxide monomers, indicating melting point as a critical predictor of mechanochemical polymerization reactivity.

Summary: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
