Carbon dioxide (CO2) has long been recognized as an ideal C1 feedstock comonomer for producing sustainable materials because it is renewable, abundant, and cost-effective. However, activating CO2 presents a significant challenge highly oxidized stable. A CO2/butadiene-derived δ-valerolactone (EVP), generated via palladium-catalyzed telomerization between butadiene, emerged attractive intermediate copolymers from butadiene. Owing to the presence of two active carbon–carbon double bonds lactone unit, EVP serves versatile creating with content up 29 wt % (33 mol %). In this Review, advances in synthesis butadiene divergent structures through various polymerization protocols have summarized. Achievements made homo- copolymerization or its derivatives are comprehensively reviewed, while postmodification obtained access new polymers also discussed. Meanwhile, potential applications The literature references were sorted into sections based on strategies mechanisms, facilitating readers gaining comprehensive view present chemistry landscape inspiring innovative approaches synthesizing novel CO2-derived copolymers.

Hybrid Monomer Design Synergizing Property Trade‐offs in Developing Polymers for Circularity and Performance

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(31)

Опубликована: Апрель 19, 2023

Abstract Current search for more sustainable plastics seeks to redesign polymers possessing both chemical recyclability monomer a circular economy and desirable performance that can rival or even exceed today's non‐recyclable hard‐to‐recycle petroleum‐based incumbents. However, within traditional framework it is challenging optimize, concurrently , contrasting polymerizability/depolymerizability recyclability/performance properties. Here, we highlight the emerging hybrid design strategy develop intrinsically with tunable properties, aiming unify desired, but otherwise conflicting, properties in single monomer. Conceptually, this hybridizes parent pairs of contrasting, mismatching, matching into offspring monomers not only above‐described conflicting also radically alter resultant polymer far beyond limits what either homopolymers their copolymers achieve.

Abstract Precisely controlling macromolecular stereochemistry and sequences is a powerful strategy for manipulating polymer properties. Controlled synthetic routes to prepare degradable polyester, polycarbonate, polyether are of recent interest due the need sustainable materials as alternatives petrochemical-based polyolefins. Enantioselective ring-opening polymerization copolymerization racemic monomers offer access stereoregular polymers, specifically enantiopure polymers that form stereocomplexes with improved physicochemical mechanical Here, we highlight state-of-the-art this chemistry can produce microstructure-defined polymers. In particular, structures performances various homogeneous enantioselective catalysts presented. Trends future challenges such discussed.

While outstanding catalysts are known for the ring-opening copolymerization (ROCOP) of CO2 and propene oxide (PO), few reported at low pressure. Here, a new series Co(III)M(I) heterodinuclear compared. The Co(III)K(I) complex shows best activity (TOF = 1728 h–1) selectivity (>90% polymer, >99% CO2) is highly effective pressures (<10 bar). insertion prerate determining chemical equilibrium step. At pressures, concentration active catalyst depends on pressure; above 12 bar, its saturated, rates independent pressure, allowing constant to be quantified first time (Keq 1.27 M–1). A unified rate law, applicable under all operating conditions, presented. As proof potential, published data leading literature reinterpreted constants estimated, showing that this law applies other systems.

Enabling Closed‐Loop Circularity of “Non‐Polymerizable” α, β‐Conjugated Lactone Towards High‐Performance Polyester with the Assistance of Cyclopentadiene

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(22)

Опубликована: Март 16, 2024

Abstract Chemical recycling of polymers to monomers presents a promising solution the escalating crisis associated with plastic waste. Despite considerable progress made in this field, primary efforts have been focused on redesigning new produce readily recyclable polymers. In contrast, limited research into potential seemingly “non‐polymerizable” has conducted. Herein, we propose paradigm that leverages “chaperone”‐assisted strategy establish closed‐loop circularity for α, β‐conjugated lactone, 5,6‐dihydro‐2H‐pyran‐2‐one (DPO). The resulting PDPO, structural analogue poly(δ‐valerolactone) (PVL), exhibits enhanced thermal properties melting point ( T m ) 114 °C and decomposition temperature d,5% 305 °C. Notably, owing similarity between DPO δ‐VL, copolymerization generates semi‐crystalline P(DPO‐ co ‐VL)s irrespective incorporation ratio. Intriguingly, inherent C=C bonds enable their convenient post‐functionalization via Michael‐addition reaction. Lastly, PDPO was demonstrated be chemically ring‐closing metathesis (RCM), representing significant step towards pursuit enabling lactones without altering ultimate polymer structure.

Polyhydroxyurethanes from Biobased Monomers and CO₂: A Bridge between Sustainable Chemistry and CO₂ Utilization^†

Chinese Journal of Chemistry, Год журнала: 2023, Номер 42(6), С. 652 - 685

Опубликована: Ноя. 7, 2023

Comprehensive Summary Polyhydroxyurethanes (PHUs) have received considerable attention in the last decade as potential alternatives to traditional phosgene‐based polyurethanes (PUs). The development of suitable 5CC (five membered‐ring cyclic carbonate) precursors bearing multiple carbonate moieties (multi‐5CCs) is a key requisite for preparing PHUs by polyaddition reaction with bis‐ or polyamines. Producing sustainable from CO 2 ‐based five‐membered carbonates (5CCs) obtained biobased epoxides valuable strategy bridge utilization and upcycling renewable substrates. In this context, while many multi‐5CC monomers reported literature are oil‐based, recent efforts led large variety multifunctional 5CCs that produced combination resources such fatty acids vegetable oils, lignin, terpenes, sugars. work, crucial advances (2019—2023) on prepared multi‐5CCs (partially/potentially) substrates reviewed respect their synthesis, thermal mechanical properties, recent, emerging applications.
