Their complexation behavior can be tuned by incorporating a controlled fraction of permanently charged quaternary ammonium units. This strategy relies on the homogeneous distribution of these units while maintaining charge-shifting properties of PDMAEA. Herein, we report the reversible addition–fragmentation chain-transfer copolymerization of 2-(<i>N,N</i>-dimethylamino)ethyl acrylate (DMAEA) and 2-acryloxyethyltrimethylammonium chloride (AETAC). Optimized conditions afford copolymers with molecular weights of 26 000–130 000 g/mol and dispersities below 1.1, with good agreement between theoretical and experimental compositions. Reactivity ratios close to unity indicate near-statistical copolymerization and a homogeneous distribution of AETAC units along the chains. Hydrolysis studies showed that incorporating up to 40 mol% AETAC negligibly influenced the rate of DMAEA hydrolysis. In contrast, isothermal titration calorimetry revealed that increasing the AETAC content resulted in three times more heparin molecules bound per copolymer chain for copolymers between 10 and 40 mol% AETAC, while reducing the number of binding contacts per heparin molecule.

Benzoxazine resins have attracted considerable attention as promising candidates due to their flexible molecular design, excellent thermal stability, low water absorption, and inherently low dielectric properties. However, most low-dielectric materials from benzoxazine systems have been developed using conventional manufacturing techniques, while their integration into additive manufacturing remains largely unexplored. In particular, adapting benzoxazine resins for vat photopolymerization (VPP) presents significant challenges because benzoxazines typically undergo thermally initiated ring-opening polymerization rather than direct photopolymerization. This review provides an overview of recent advances in the development of photoreactive benzoxazine systems and VPP-compatible resin formulations. Particular emphasis is placed on molecular design strategies, the incorporation of photocurable functional groups, control of resin viscosity, and dual-curing mechanisms that combine photocuring with subsequent thermal ring-opening polymerization. The reported studies demonstrate promising progress toward the fabrication of benzoxazine-based structures with favorable thermomechanical performance and processing feasibility. Furthermore, this review critically discusses current formulation strategies and emerging design principles for developing low-dielectric benzoxazine resins.

A key challenge in such systems is overcoming the inherent trade-off between proton conductivity and dimensional stability. Herein, we report the design and synthesis of two series of fluorine-free, pyridinyl-based sulfonated proton exchange membranes, namely polytriazoles (ODPYSH-XX) and poly(sulfone triazole)s (SOPYSH-XX), prepared via Cu-catalyzed click copolymerization with high degrees of sulfonation (DS = 80 and 90). Both membrane series exhibit excellent thermal, mechanical, and dimensional stability.
