| Abstract: | Monodisperse carboxyl-functionalized superparamagnetic polymer microspheres were prepared by modified seed-emulsion copolymerization.The properties of obtained microspheres were characterized by transmission electron microscopy(TEM),thermogravimetric analysis(TGA) and vibrating sample magnetometry(VSM).The features of TGA curves of functionalized magnetic polymer microspheres and the changes of component during the measurements were revealed by a systematic analysis via thermogravimetry and mass spectrometr... |
