This article contains original experimental data, figures and methods to the study of Microwave-assisted emulsion polymerization of styrene under the frame of "Enhanced Microwave Synthesis" (EMS), has been examined to investigate the advantages of Microwave (MW) power use in emulsion polymerization (Ergan el. al., Fur. Polym. J. 69, 2015, 374-384). For comparative purpose, MW and conventional healing (CH) method experiments were conducted under similar conditions. By externally cooling the reaction vessel with 1,4-dioxanc, constant and continuous MW power was successfully applied at isothermal condition during the polymerization. Here we give the MW power calibration data of MW-experimental system, the complete set of the experimental polymerization data and the analysis data obtained from different polymer characterization test devices (GPC, DSC and Viscometer).
