The water expandable beads were prepared through surfactant free Pickering emulsion polymerization of styrene in water/oil/water (w/o/w) system using cellulose nanofibrils (CNF). The water microdroplets were shown to be surrounded by a dense layer of CNF/polystyrene composite (CNF/PS) nanospheres ...

In emulsion polymerization processes, the surfactant concentration plays an important role in the latex stability, reaction kinetics and particle size distribution (PSD). Controlling the free surfactant concentration in the aqueous phase ensures the stability of the latex and the control of the micellar...
The preparation of the emulsion polymer of the invention is carried out in two stages. (1) In the first stage there is produced a conventional carboxyl group-containing polymer by a conventional solution or bulk polymerization technique. The polymer is then water-dispersed (or solubilized) by par...
Surfactant-free coupling polymerization of pyrrole (Py) and its derivatives, namely, N-methylpyrrole (MPy) and N-ethylpyrrole (EPy), was conducted using solid Fe(NO3)3 in the presence of an aqueous medium, resulting in aqueous dispersions of polymer part
The combination of reversible addition–fragmentation chain transfer (RAFT) and emulsion polymerization has recently attracted much attention as a synthetic tool for high-molecular-weight block copolymers and their micellar nano-objects. Up to recently, though, the use of thermoresponsive polymers as both...
Also provided is a surfactant for emulsion polymerization which comprises as an essential ingredient a surfactant represented by the general formula (I): R 1 -O-(AO) n -R 2 (wherein R 1 represents C 1-24 branched or linear alkyl, C 1-24 aryl, or aryl having C 8-18 alkyl; A ...
