Aqueous solutions of various types honey as a source reducing sugars – glucose and fructose, were used to accelerate or control activators regeneration by electron transfer atom radical polymerization (ARGET ATRP) in homogeneous heterogeneous environment. The aqueous alcoholic-aqueous solution was applied for the hydrophilic methacrylates i.e. 2-(dimethylamino)ethyl methacrylate (DMAEMA), glyci...

Composites of a styrene-isoprene copolymer and SWNTs were prepared by emulsion and miniemulsion polymerization in the presence of SWNTs, aswell as bymixing dispersed SWNTs with a styrene-isoprene copolymer latex after polymerization. For the former, the surfactant was displaced from SWNTs to monomer droplets leading to SWNT aggregation. Mixing dispersed SWNTs with latex after reaction was able ...

Porous hyperbranched conjugated polymer nanoparticles with an average particle size of 20-60 nm and a specific surface area of 225 m(2) g(-1) have been prepared through Suzuki polymerization in a miniemulsion, which could be stably dispersed in common organic solvents after complete removal of surfactants. Furthermore, a simple spin-coating method for the preparation of homogeneous transparent ...

Macromonomeric azo initiators (macroinimers, MIM) which have the properties of macromonomers, macrocrosslinkers and macroinitiators in a macrostructure were used in miniemulsion polymerization of styrene in the presence or absence of any other stabilizer and initiator. MIMs were prepared from the reaction of 4,40-dicyano-4,40-azovaleryl chloride, with poly(ethylene glycol) (PEG) of different mo...
