摘要：A novel bismaleimide monomer 2,2'-Bis[4-(4-maleimidophenoxy)phenyl]-hexafluoropropane(BAPOFP-BMI) was prepared by using maleic anhydride and 2,2'-bis(4-(4-amino- phenoxy)phenyl)hexafluoropropane, with toluene and N,N'-Dimethylformamide as the solvents. The monomer was characterized by means of FT-IR spectra, H-1 NMR, MS and element analysis. The result of HPLC shows that the purity of BAPOFP-BMI is 97.4%, melting point of BAPOFP-BMI is 153.2 degrees C and curing exothermic peak is 290 degrees C, which means that BAPOFP-BMI has a relatively wider processing window. Moreover, BAPOFP-BMI has better solublility in a variety of organic solvents. Further experiments indicate that BAPOFP-BMI has better dielectric properties and thermal performance compared with o-diallyl-bisphenol-A-modified N,N'-(4,4'-diphenylmethane) bismaleimide (MDA-BMI/DABPA), too.
