“…Styrene–acrylic emulsions are widely used as industrial maintenance coating for the acrylate unit’s resistance to photodegradation and the styrene unit’s resistance to hydrolysis [ 1 , 2 ]. Furthermore, styrene–acrylic emulsions are also used for preparing nanoparticles [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ], which are applied in the treatment of bacterial infections [ 10 , 11 ] or encapsulation medicine [ 12 , 13 ]. The optionality of the monomer endows emulsion polymers with some special properties.…”

“…Styrene–acrylic emulsions can be prepared via emulsion polymerization with or without an emulsifier. Emulsion polymerization with a nonpolymeric emulsifier is conducted via the polymerization of weak water-soluble monomers within the emulsion of a nonpolymeric emulsifier [ 11 ]. In emulsifier-free polymerization, an initiator [ 20 ] or water-soluble monomer [ 21 ] can act as a polymeric emulsifier.…”

Styrene–acrylic emulsions containing hydroxyl functional monomer unit’s component are widely used for maintenance coating. In this paper, a stable emulsifier-free styrene–acrylic emulsion with solid content over 43% could be obtained in 210 min via reverse iodine transfer polymerization (RITP). By adding a mixture of methacrylic acid (MAA) and poly(ethylene glycol)methyl ether methacrylate (PEGMA) into a system containing a high content of hydroxyl functional monomer component (19.4 wt.% of the total monomer mass), styrene (St) could be copolymerized with methyl methacrylate (MMA); the modified film exhibited good hardness properties, good adhesive properties, and low water absorption. An increase in the amount of PEGMA decreased the glass transition temperature (Tg). When 1.4 times the reference amount of initiator was added, the highest molecular weight Mn could reach 40,000 g.·mol−1 with 0.25 times the reference amount of iodine in the emulsion. The largest tensile strength of the dried emulsion film over 5.5 MPa endowed the material with good mechanical properties. Living polymerization was proven by the kinetics of RITP emulsion and chain extension reaction. TEM micrographs manifest the emulsification of the seed random copolymer. This paper may provide a potential methodology for preparing polymer materials with excellent mechanical properties.
