A methacrylic-acrylic polymer was synthesised for use as a non-plasticised membrane for hydrogen ion-selective sensor incorporating tridodecylamine as an ionophore. The copolymer consisted of methyl methacrylate and n-butyl acrylate monomers in a ratio of 2:8. Characterisation of the copolymer using FTNMR demonstrated that the amount of each monomer incorporated during solution polymerisation w...

Polymerization-induced self-assembly (PISA) has become a widely used technique for the rational design of diblock copolymer nano-objects in concentrated aqueous solution. Depending on the specific PISA formulation, reversible addition-fragmentation chain transfer (RAFT) aqueous dispersion polymerization typically provides straightforward access to either spheres, worms, or vesicles. In contrast...

INTRODUCTION Acrylic resins containing acrylic acid (AA), methyl methacrylate (MMA) or acrylic–methacrylic copolymer are the most commonly used polymeric materials for biomedical and pharmaceutical applications owing to their hydrophilicity and biocompatibility.1–4 Recently, a new polyvinyl alcohol (PVA) copolymer designed by copolymerizing AA and MMA with PVA was successfully developed as a ca...

We studied the allergic reaction of guinea pigs to glyceryl methacrylate (GM), hydroxyethyl methacrylate (HEMA) and meso-erythritol methacrylate (EM), which are used as dentin primers. On the 18th day of the application test, when macroscopic investigation revealed an inflammatory reaction, the methacrylic acid-treated group showed marked eschar formation in comparison with the control group. I...

The diffusivity and distribution of water in the butyl methacrylate and methacrylic acid copolymer films swollen in water have been investigated using the NMR relaxation and pulse field gradient (PFG) NMR techniques. The contributions of polymer matrix protons, surface water and bound water have been determined from H NMR spectra and relaxation functions. PFG NMR experiments showed that the ech...

Fluorescent clusters of several Ag atoms are fluorophores with a large set of attractive properties including sub-nanometer size, high fluorescence quantum yield and large Stokes shift. When formed on polymeric scaffolds they exhibit a broad range of heterogeneities in excitation and emission spectra. Addressing this issue we provide detailed spectroscopic studies of these clusters produced by ...

We describe the synthesis and the solution properties of Janus micelles containing a polybutadiene (PB) core and a compartmentalized corona consisting of a poly(methacrylic acid) (PMAA) and a polystyrene (PS) hemisphere. The Janus micelles were obtained via cross-linking the middle block of a microphase-separated PS-block-PB-block-PMMA triblock copolymer in the bulk state, followed by alkaline ...

Synthesis, characterization and cytotoxicity evaluation of copolymers based on polyethylene glycol monmethyl ether-g-poly(methacrylic acid-co-methyl methacrylate) are reported via a polymeric precursor method. Grafting was accomplished based on direct condensation reaction in the presence of dicyclohexylcarbodiimide as an esterification-promoting agent catalyzed by dimethylamino pyridine. Polye...
