Bioinspired, Guanidinium, and Indole Modified Poly(glycidyl ether)s as Highly Efficient Vectors for Polyplex‐Mediated Gene Delivery

Macromolecular Rapid Communications, EarlyView.
Guanidinium‐ and indole‐functionalized poly(glycidyl ether)s were developed as non‐viral gene delivery vectors with tunable hydrophilic–hydrophobic balance. All polymers formed stable DNA polyplexes, while moderate indole content yielded the highest transfection efficiency at low N/P ratios.

Toward Dynamic Liquid Cell Scaffold: Photoreversible Ion Gels Exhibiting Light‐Induced Sol‐Gel Transitions

Macromolecular Rapid Communications, EarlyView.
Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.

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 ...

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.
