It has been found that even very small amounts of MWCNTs (0.01¨C0.1 wt%) catalyze the reaction of polycyclotrimerization of DCBA leading to formation of polycyanurate network (PCN)/MWCNTs nanocomposite. However, some decrease in final degree of conversion for nanocomposites compared to the neat PCN within the temperature/time schedule used was observed. The kinetic rate constants increased with addition of MWCNTs and energies of activation were found to be significantly decreased even at low contents of MWCNTs. %K Nanocomposites %K Thermosetting polymers %K Polycyanurates %K Carbon Nanotubes %K Sonication %U http://www.expresspolymlett.com/letolt.php?file=EPL-0000970&mi=cd
