Methylacrylic acid (MAA), acrylonitrile (AN), acrylamide (AM) and methyl methacrylate (MMA) were polymerized by γ-rays, and AN/AM/MAA copolymer as well as polymethylmethacrylate (PMMA) were synthesized. Then microporous structure of polymethacrylimide (PMI) was obtained by the degradation of PMMA using heat-treatment. FIIR spectra showed that imide process and PMMA degradation were simultaneous at the selected temperature. TG-DSC analysis showed that the sample began to degrade at 345℃. And SEM photos indicated that microporous PMI with obturator foramen structure was obtained, whose aperture was about 100 µm.
