Abstract Transparent ABS resin was prepared by continuous bulk polymerization using a pilot plant in series with multiple reactors. By measuring and studying the microstructure and physical properties of polymer the influence of different polymerization temperature on the structure and properties of bulk transparent ABS was explored. The results showed that lower polymerization temperature was beneficial to increase the molecular weight of MABS narrow the molecular weight distribution and improve the grafting rate of rubber. Low polymerization temperature was adverse to improve the processing fluidity but it could improve the toughening effect of rubber enhance the impact strength of transparent ABS resin and help to boost the heat resistance. The transparency of ABS resin was significantly affected by the polymerization temperature. High polymerization temperature made the resin yellow while the light transmittance decreased and the haze increased significantly. The optimum polymerization temperature 115 ℃ 2 h135 ℃ 2 h145 ℃ 4 h were obtained by synthesizing various properties. The transparent ABS resin prepared under these conditions has excellent transparency good mechanical properties heat resistance and processing fluidity.
