The optionality of the monomer endows emulsion polymers with some special properties. Furthermore, styrene–acrylic emulsions are also used for preparing nanoparticles, which are applied in the treatment of bacterial infections or encapsulation medicine. 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. This paper may provide a potential methodology for preparing polymer materials with excellent mechanical properties. TEM micrographs manifest the emulsification of the seed random copolymer. Living polymerization was proven by the kinetics of RITP emulsion and chain extension reaction. The largest tensile strength of the dried emulsion film over 5.5 MPa endowed the material with good mechanical properties. mol −1 with 0.25 times the reference amount of iodine in the emulsion.When 1.4 times the reference amount of initiator was added, the highest molecular weight M n could reach 40,000 g. An increase in the amount of PEGMA decreased the glass transition temperature ( T g). 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. 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).

Styrene–acrylic emulsions containing hydroxyl functional monomer unit’s component are widely used for maintenance coating.
