Biocompatible Sulfobetaine Polymer‐Artemisinin Conjugates Inducing Ferroptosis in Cancer Cells: Synthesis by Mechanochemical Solid‐State Polymerization and Characterization

Macromolecular Rapid Communications, EarlyView.
The amphiphilic copolymer incorporating a hydrophobic chain conjugated with artesunate into a biocompatible sulfobetaine polymer is synthesized by solid‐state copolymerization of sulfobetaine methacrylate and methacrylamide derivative conjugating artesunate.

Dynamics of Poly(Vinyl Acetate)-d₃ on Silica [PDF]

, 2001
Poly(vinyl acetate) (PVAc) is an important polymer in applications because of both its bulk and surface characteristics. Its chain architecture gives it a low Tg and, generally, good qualities for processing and applications, which include paints ...

Synthesis of Borneol‐Polymers as Fluorescent Sensors for Pollutant Detection

Macromolecular Symposia, EarlyView.
ABSTRACT In this work, a borneol‐derived monomer was employed to synthesize two novel copolymers, poly(vinyl acetate‐co‐bornyl methacrylate) (CopBM‐1) and poly(p‐acryloyloxybenzaldehyde‐co‐bornyl methacrylate) (CopBM‐2), via radical copolymerization. Both copolymers demonstrated aggregation‐induced emission in DMF at concentrations exceeding 0.04 wt.%.

A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

Macromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

Lipase specificity for the hydrolysis of poly (vinyl acetate) [PDF]

, 2003
The effect of lipases on the side chain hydrolysis of poly (vinyl acetate) (PVAc) was investigated in toluene by various lipases, Hog-pancreas (HP), Candida Rugosa (CR), Lipolase-100T (LL), and Novozyme 435 (NV)at 60 degreesC.
