Preparation of CO2-Switchable Poly(Methyl Methacrylate) Latexes by Surfactant-Free Emulsion Polymerization
… switchable poly(methyl methacrylate) latexes by surfactant-free emulsion polymerization. N,N-Dimethylaminoethyl Methacrylate (DMAEMA) was chosen as the functional comonomer to act as an in-situ generated surface active agent as well as the CO2 responsive agent. The azo initiator …

pH-sensitive core-shell nanoparticles for intracellular drug delivery
… cell binding, and drug binding. Two-stage surfactant-free emulsion polymerization of 2-diethylamino ethyl methacrylate (DEAEMA) (core) and 2-amino ethyl methacrylate (AEMA) (shell) in the presence of a crosslinker was used for the synthesis of monodisperse core-shell hydrogel nanoparticles …

Controlling the interfacial behaviour of colloidal microgel systems
… colloidal microgel particles were prepared by a surfactant-free emulsion polymerization of N-isopropylacrylamide (NIPAM) with more hydrophobic vinyl ether/ester/silane co-monomers (10 % total mass monomer). Most of the resultant dispersions were novel co-polymer microgels and all exhibited a …

Nucleation in emulsion polymerization : steps towards a non-micellar nucleation theory
… of the mechanism of particle nucleation in emulsion polymerization has been one of the most challenging issues in heterophase polymerization research. Within this work a comprehensive experimental study of particle nucleation in emulsion polymerization of styrene at 70 °C and variety of …

Experimental spectroscopic and theoretical studies of organic compounds and polymeric structures
… the original reaction mixture) were prepared by surfactant-free emulsion polymerization. Freeze-dried samples of the microgels were subjected to analysis by Raman spectroscopy using 632.8 nm exciting radiation from a helium-neon laser. The Raman spectral profiles of the different microgels are …
