Poly(Imino Ketone)(PIK) is a group of novel high performance polymer material with excellent thermal properties and dissolubility. Aiming at the requirements of inertial confined fusion(ICF) studies on low density polymer foams, we firstly synthesized poly(imino imino ketone)(PIIK) by palladium catalyzed C-N cross-coupling reaction, and successfully prepared the PIIK foam material with a density of 80-300 mg/cm3 by using PIIK as the raw material with thermal-induced phase separation and lyophilization technique. Mercury injection method was used to determine the structure of PIIK foams, and the results indicated that the mean pore diameter was lower than 5 μm and it had relatively high voidage and specific surface area.
