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

Macromolecular 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

Temperature‐Driven Switching Between Block, Near‐Statistical, and Gradient Copolymers Enabled by Multinuclear Aluminum Catalysis

Macromolecular Rapid Communications, EarlyView.
A single multinuclear aluminum catalyst enables temperature‐driven switching between block‐enriched, near‐statistical, and gradient CL/LA copolymer microstructures. Modulation of propagation and exchange processes within one catalytic platform provides a unified kinetic–thermodynamic framework for sequence control in biodegradable polyester ...

Exploring 2‐D σ−σ* Conjugation in Cyclic Polysiloxane Copolymers

Macromolecular Rapid Communications, EarlyView.
We find σ−σ * conjugation in copolymers synthesized by reacting the cyclomer [vinylMeSiO]4 in a 1:1 ratio with various Br‐Ar‐Br. Further, on modifying the remaining unsubstituted viny groups with Br‐Ar’, we change the main chain photophysics. However, as a test, we also appended Br‐Ar’ groups on the cylomer alone observing σ−σ * conjugation coincident ...

Influence of Adding Cyclodextrin Derivatives on the Mechanical and Thermal Properties of Glassy Polymers

Macromolecular Rapid Communications, EarlyView.
Triacetylated γ‐cyclodextrin incorporated into poly(methyl methacrylate) primarily acted as a rigid filler and reinforced the matrix polymer, with the reinforcement behavior following the Guth–Gold equation. In addition, the glass transition temperature was maintained upon incorporation, indicating that the additive did not plasticize the polymer ...

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.%.
