摘要: Abstract not available for EP0628062Abstract of corresponding document: WO9317069An isotropic, biaxially stretched polyimide film prepared by casting a solution polyamic acid precursor in an organic solvent containing cyclization catalyst and dehydrating agent onto the surface support, imidizing to give continuous self-supporting gel 5-50 % weight solids, stretching machine direction (MD) at ratio 1.1-1.9, transverse (TD) with respect so as maintain TD/MD stretch from 0.9 1.3.
