【Abstract】 s A novel benzoxazine precursor was synthesized by reaction of diphenyl oxide resin,phenol,formaldehyde and aniline.The reaction conditions were studied in detail and the synthesized products were characterized by IR and NMR.The curing behavior and thermal stability of the products were investigated by DSC and TG.The results showed that the synthesized product conformed to designed product,and that the temperature with 5 Wt% loss of resin was 399℃更多还原
