| Abstract: | The N-phenyl maleimide(N-PMI) modified novolac resin was used to prepare resin microspheres via suspension polymerization using silicone oil as dispersant.The morphology of N-PMI modified novolac resin microspheres was investigated through scanning electron microscope(SEM).The thermal behavior of the resin microspheres was studied by thermogravimetric analysis(TG-DTG).Moreover,The chemical structures of the resin microspheres at different pyrolysis temperature were characterized by Fourier transform infrared spectrum(FT-IR).The results show that the resin microspheres with size of 10 μm～20 μm have fine degree of sphericity and smoothness.The resin microspheres possess excellent thermal properties as indicated by that initial thermal decomposition temperature is 400 ℃ and coke value arrives at 61.8 %.Moreover,the pyrolysis products of the resin microspheres are made up of carbon spheres with fine degree of sphericity. |
