This communication describes a convenient route to optically active propylene carbonate by catalytic kinetic resolution process resulting from the coupling reaction of CO2 and racemic epoxides using simple chiral SalenCo(III)/quaternary ammonium halide catalyst systems.
Vitrimers endow cross-linked polymers with malleability and reprocessability via exchange reactions. However, designing of reprocessable, shape-memory polymer materials high strength a catalyst-free method remains challenge under mild conditions. Here, we propose facile strategy to address this dilemma by introducing the exchangeable imine bond N-coordinated boroxine into polybutadiene (PB)-based network. Specifically, PB grafted 2-aminoethanethiol is reacted formyl group phenylboronic acid...
A covalent adaptable network can endow rubber materials with recyclability and reprocessability is expected to alleviate black pollution caused by end-of-life rubber. However, the loss of traditional vulcanization systems severely sacrifices their strength, tensile strength in current study rarely exceeds 10 MPa unless fillers are added. In this work, we proposed a self-strengthening process based on dual-dynamic units (imine disulfide), briefly, under heating, phenylsulfur radicals...
Synthetic rubbers fabricated from 1,3-butadiene (BD) and its substituted monomers have been extensively used in tires, toughened plastics, many other products owing to the easy polymerization/copolymerization of these high stability resulting material manufacturing operations large-scale productions. The need for synthetic with increased environmental friendliness or endurance harsh environments has motivated remarkable progress synthesis BD recent years. We review developments an emphasis...
Abstract High cis ‐1,4 polyisoprene with narrow molecular weight distribution has been prepared via coordinative chain transfer polymerization (CCTP) using a homogeneous rare earth catalyst composed of neodymium versatate (Nd(vers) 3 ), dimethyldichlorosilane (Me 2 SiCl and diisobutylaluminum hydride (Al( i ‐Bu) H) which strong affinity is used as both cocatalyst agent (CTA). Differentiating from the typical shuttling where dual‐catalysts/CSA system used, one catalyst/CTA in this work,...
A carbonaceous solid acid catalyst with −Cl and −SO3H groups was facilely synthesized in one step by the co-carbonization of sucralose p-toluenesulfonic acid. The as-prepared used for hydrolysis cellulose into glucose aqueous solutions. When first mixed ball milling, process provided a yield 52.8% pure water at 200 °C within 1 h, yields increased to 71.9% 88.0% dilute 0.02 wt % H2SO4 HCl (with same proton content) solutions, respectively. excellent catalytic activity production from ascribed...
Abstract Vitrimerization of thermoset polymers plays an important role in addressing resource recovery and reuse. Vitrimer elastomers with good mechanical properties often require well‐designed crosslinking agents or fillers, but this increases processing complexity reduces vitrimer dynamic properties. In report, a simple green strategy to build strong elastomer is designed. Commercially available epoxidized natural rubber (ENR) cross‐linked biomass‐derived D‐Fructose 1,6‐bisphosphoric acid...
The vast majority of traditional vulcanized rubber products are insoluble and infusible, which is difficult to reprocess biodegrade, resulting in black pollution. In addition, although most materials based on covalent adaptive networks (CANs) can achieve structural reconstruction, the lack vulcanization system leads a decline strength. this study, biobased vanillin derivatives (PV) were synthesized cross-link commercially available 1,2-polybutadiene precursor construct imine-based CANs,...
Bulk-edge correspondence (BEC) constitutes a fundamental concept within the domain of topological physics, elucidating profound interplay between invariants that characterize bulk states and emergent edge states. A recent highlight along this research line consists establishing BEC under eigenvalue's nonlinearity in linear Hamiltonian by introducing auxiliary eigenvalues [\href{https://doi.org/10.1103/PhysRevLett.132.126601}{ T. Isobe {\it et al.,} Phys. Rev. Lett. 132, 126601 (2024)}]. The...
Multiblock copolymers of cis-1,4- and trans-1,4-polybutadiene (PBD) have shown exciting unique elastic properties. But the catalyst that can steadily regulate content distribution stereoselective monomers in PBD copolymer is full challenge. We reported here a ternary Nd(CF3SO3)3·H2O·3TBP/Mg(n-Bu)2/MMAO (TBP: tributyl phosphate; MMAO: modified methylaluminoxane) synthesize such via chain shuttling polymerization highly efficient tunable way. The stereoselectivity cis-1,4 trans-1,4 be well...
