The　copolymer　of　allyl　condensed　polynuclear　aromatic　(COPNA)　resin　and　4,4＇-bismaleimidodiphenyl　methane　(BMI)　was　used　to　prepare　resin　microspheres　using　silicone　oil　as　dispersant　by　means　of　suspension　polymerization,　and　solid　carbon　spheres　were　prepared　by　direct　pyrolysis　of　the　resin　microspheres　in　this　paper.　Thermal　behavior　of　the　resin　microspheres　was　studied　by　TG-DTG,　FTIR　and　element　analyze　instrument.　The　resultant　carbon　spheres　were　characterized　by　SEM,　XRD　and　nitrogen　adsorption-desorption　measurement.　Results　show　that　the　resin　microspheres,　which　have　a　mean　particle　diameter　of　14.6　mu　m,　possess　fine　degree　of　sphericity　and　smoothness.　The　resin　microspheres　possess　excellent　thermal　properties,　indicated　by　that　initial　decomposition　temperature　is　420　degrees　C　and　carbonization　yield　reaches　49.1%　in　nitrogen.　Furthermore,　pyrolysis　products　of　the　resin　microspheres　are　made　up　of　solid　carbon　spheres　with　a　nongraphitized　carbonaceous　structure.　When　pyrolysis　temperature　is　1000　degrees　C.　the　BET　surface　area　and　total　pore　volume　of　the　carbon　spheres　arrive　at　595　m(2)　g(-1)　and　0.29　cm(3)　g(-1),　respectively.　(c)　2010　Elsevier　B.V.　All　rights　reserved.
