摘　　要：A nitrile butadiene elastomeric nanoparticle (NBENP) was used for modification of resol phenolic resin.The reaction between NBENP and resol was measured by FT-IR,and the curing behavior of resins was charactered by DSC.The mecanical and thermal properties of modified resins were measured.Fra cture surface of modified phenolic resin was observed by SEM.The results showed that,the impact strength, flexural strength and heat resistance of NBENP modifie d phenolic resin were increased at the same time. A strong interface adhesion wa s formed because of the reaction between hydroxymethyl of resol and NBENP.This s pecial interface conduces to transmission of stress when materials were loaded,a nd inhibition of deformation and decomposition of phenolic matrix when heated.Th e microcrack,initiated with rubber particle,and cavitation of rubbers might be t he main reason for increase in toughness.The honeycomb structure in fracture sur face might be another possible reason for excellent mechanical properties.
