Large-scale and narrow dispersed latex formation in batch emulsion polymerization of styrene in methanol–water solution

Facile synthesis of large scale and narrow particle size distribution polymer particles via control particle coagulation during one-step emulsion polymerization

“…In contrast, the effect of the addition of methanol on particle coagulation in our previous studies [22] indicated that the addition of methanol decreased the interfacial energy between particle surface and the aqueous phase, and thus the surfactant molecules became loosely adsorbed on the particle surface, leading to the decreases in the repulsive potential energy and increase in the attractive potential energy [40][41][42].…”

“…To enhance the particle coagulation, the polymerization was carried out in the methanol solution (30 wt%) similar to the literature procedure [22,23].…”

“…In our previous reports [22][23][24], the particle coagulation induced by electrolyte or methanol was investigated in the conventional emulsion polymerization by tracking the evolution of the particle size and number as a function of polymerization time;…”

Synthesis of Sub-100 nm and Narrow Particle Size Distribution Cationic Latex by One-Step Emulsion Polymerization

“…The detailed measuring process could be obtained in our previous reports. [14][15][16] 3. RESULTS AND DISCUSSION…”

“…[14][15][16] However, these investigations were carried out in the anionic systems using sodium dodecyl sulfate (SDS) and potassium persulfate (KPS) as surfactant and initiator, respectively. In this study, the cationic emulsion copolymerization of styrene and butyl acrylate would be performed in the presence of a range of cationic surfactants by varying monomer/water ratios and monomer composition.…”
