Abstract

A novel kind of cyanate ester CE/epoxy resin microspheres have been synthesized using the polymerization technology of cyanate ester and epoxy resin in anhydrous ethanol media surfactant sodium dodecylbenzene sulfonate was used as an emulsifier and imidazole was used as catalyst or curing agent The morphologies chemical structures and thermal properties of microspheres were investigated by Fourier transform infrared spectroscopy scanning electron microscope laser scanning confocal fluorescence microscopy optical microscope differential scanning calorimeter and thermogravimetric analyzer respectively The effects of process parameters such as the amount of imidazole and the weight ratio of epoxy resin to CE on the size and morphology of microsphere were discussed Results indicate that the reactivity and surface morphology of microsphere can be adjusted by the amount of imidazole and the weight ratio of epoxy resin to CE The prepared microsphere shows excellent thermal stability and good reactivityWe thank the National Natural Science Foundation of China No50903058 Provincial Natural Science Foundation of Jiangsu NoBK2009124 China Postdoctoral Science Foundation No20080440165 and Jiangsu Provincial Postdoctoral Science Research Sustentation Fund No0802019B We also thank the Analysis and Testing Center of Soochow University
