Preparation of Poly(oxybutyleneoxymaleoyl) Catalyzed by a Proton Exchanged Montmorillonite Clay

open access: yesMolecules, 2004
The polycondensation of tetrahydrofuran with maleic anhydride catalyzed byMaghnite-H+ (Mag-H) was investigated. Maghnite is a montmorillonite sheet silicateclay that is exchanged with protons to produce Maghnite-H [1]. It was found that thepolymerization

Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

open access: yesFlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

Polarographic reduction of maleic anhydride, maleate and fumerate in pyridine [PDF]

open access: yes, 1967
Maleic and fumaric acids in pyridine show only the reduction behaviour of the pyridinium ion, which is produced when any Bronsted acid of aqueous pKa less than ca 9 is dissolved in pyridine.

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

open access: yesMacromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

open access: yesMacromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Carbon monoxide oxidation by oxygen in water-acetonitrile solutions of palladium(II) bromide complexes in the presence of Co(II), Fe(II) and Mn(III) phthalocyaninates

open access: yesТонкие химические технологии, 2019
Objectives. The objective of this paper was to compare acetylene oxidative dicarbonylation that leads to maleic anhydride with a side reaction of CO oxidation by oxygen in a PdBr2-LiBr-H2C-CH3CN system and in the presence of insoluble (Co) and soluble ...

3D-Printed Biocomposites from Hemp Fibers Reinforced Polylactic Acid: Thermal, Morphology, and Mechanical Performance

open access: yesBioResources
Thermal, morphological, and mechanical properties were studied for 3D-printed biocomposites prepared from polylactic acid (PLA) and hemp fibers. For this purpose, the neat PLA, PLA/Hemp fiber (3 wt%), PLA/Hemp fiber/Maleic anhydride (3 wt% and 0.6 wt ...
