Kafetzi, Martha published the artcileMultifaceted pH and Temperature Induced Self-Assembly of P(DMAEMA-co-LMA)-b-POEGMA Terpolymers and Their Cationic Analogues in Aqueous Media, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is amphiphilic polymethacrylate diblock terpolymer self assembly RAFT polymerization.
This work focuses on the synthesis of novel amphiphilic block terpolymers of the type poly[(2-(N,N-dimethylamino) Et methacrylate)-co-(lauryl methacrylate)]-b-poly[(oligo ethylene glycol) Me ether methacrylate] (P(DMAEMA-co-LMA)-b-POEGMA) by reversible addition-fragmentation chain transfer polymerization The cationic amphiphilic polyelectrolyte analogs P(QDMAEMA-co-LMA)-b-POEGMA are obtained through quant. quaternization of the DMAEMA segments. Mol. characterization by size exclusion chromatog., NMR, and Fourier Transform IR spectroscopies indicates the successful synthesis of these novel series of block terpolymers. The amine forms of the block copolymers respond to pH and temperature changes in aqueous solutions by forming unimol. or multichain nanoaggregates of varying size, micropolarity, and internal structure, as indicated by light scattering and fluorescence spectroscopy techniques. At neutral and basic pH, the existence of micellar like nanoassemblies is observed in the solutions of P(DMAEMA-co-LMA)-b-POEGMA terpolymers, while aggregation into micellar-like clusters take place at temperature values above room temperature due to the presence of the hydrophobic LMA segments. Unexpectedly, the cationic polyelectrolytes P(QDMAEMA-co-LMA)-b-POEGMA counterparts show temperature responsiveness as a consequence of the amphiphilicity of the polymeric system.
