Compositional Determination of Vinyl Acetate/Vinyl Benzoate Copolymer by Fourier Transform Infrared Spectroscopy [PDF]
علوم و تکنولوژی پلیمر, 2015 Relating polymer structure to its performance properties is a primary motivation for determining the structure of a polymer chain. If a polymer chain is completely characterized and the structural basis of its properties is known, one can optimize and ...

Miscibility of poly(vinyl chloride) and poly(vinyl acetate) [PDF]
Macromolecules, 1991 In contrast to the results of Coleman and co-workers, blends of PVC and PVAc docained in two different ways (solvent casting from methyl ethyl ketone and freeze-drying of a dioxane solution) are found to be phase ...

Kinetics of Emulsion Copolymerization of Vinyl Acetate and Vinyl Pivalate [PDF]
Polymer Journal, 1996 Vinyl acetate (VAc) and vinyl pivalate (VPi) were homopolymerized and copolymerized by low-temperature redox emulsion polymerization using a manganese chelate as initiator. The polymerization kinetics in these systems were investigated by a mathematical model and estimating the respective kinetic parameters. Among the parameters, the radical entry rate

Advanced Functional Materials, EarlyView.Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...

Advanced Healthcare Materials, EarlyView.Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Advanced Materials, EarlyView.In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.

Advanced Materials Interfaces, EarlyView.Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...
