【Abstract】 The preparation of a novel polyetherimide(PEI-A) with low T_g was reported in this paper.The BMI resin microspheres with 3～5 μm diameter were prepared by the blend of PEI-A/BMI monomer and diallyl bisphenol (DBA),through reaction-induced phase separation.The result showed that the system of PEI-A/BMI monomer and DBA was suitable to prepare BMI resin microspheres with micrometer size.With increase of PEI-A content (as below 50 percent),bismaleimide resin microsphere particle size decreases,but their particle size distributions became narrow.更多还原
