Activators regenerated by electron transfer (ARGET) atom radical polymerization (ATRP)-based aqueous miniemulsion where the takes place in stabilized monomer droplets is described. In this work, we compared styrene, n-butyl methacrylate (nBMA) and tert-butyl (tBMA) investigated influence of their hydrophobicity on dispersity, molecular weight particle stability based partition coefficients (log...

ethyl benzene used increasingly each year is the raw material of producing styrene monomer. this substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. in this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...

In this paper we have studied the effect of copolymerization of a non-ionic but hydrophilic monomer on the interfacial properties of the latex surface. Hydrophilic polymer colloids were prepared by the emulsifier-free emulsion copolymerization of styrene and 2-hydroxyethyl methacrylate (HEMA) with potassium persulfate as initiator. The copolymer compositions were evaluated by 1H nuclear magneti...

In this work, the structural features of spherical gold nanoparticles (NPs) decorated with highly grafted poly(styrene) (PS), poly(vinylpyridine) (PVP) and PS-PVP diblock copolymer brushes immersed in a good solvent are investigated by means of Dissipative Particle Dynamics (DPD) simulations as a function of grafted chain length and of homopolymer and copolymer chain composition. For NPs grafte...

Emulsifier-free poly(methyl methacrylate-styrene) [P(MMA-St)] nanospheres with an average particle size of 100 nm were synthesized in an isopropyl alcohol-water medium by a solvothermal method. Then, through radical graft copolymerization of thermo-sensitive monomer N-isopropylacrylamide (NIPAm) and hydrophilic monomer acrylic acid (AA) onto the surface of P(MMA-St) nanospheres at 80 °C, a seri...
