摘要：
New copolyimides containing hexafluoroisopropylidene moieties were prepared by two-step solution polycondensation reaction of hexafluoroisopropylidene-bis(phthalic) dianhydride with a mixture of two aromatic diamines one of them containing a pendent substituted azobenzene group. The thermal stability and photo-optical properties of these copolyimides were measured and compared with those of wholly aromatic polyimides.
