PURPOSE:To facilitate the formation of an Si- or Ge-containing ultrathin heat- resistant polymer film by feeding a solution of a specified soluble polymer onto the surface of a support, laminating the formed ultrathin polymer film on a substrate by adhesion and heat-treating this film. CONSTITUTION:A solution of an alternate or block copolymer of formula I (wherein R1 is H, a 1-9C alkyl, a haloalkyl or a phenyl; R2 is a 1-9C alkyl, a haloalkyl or a phenyl n>=10; or X is a group comprising a residue containing C, B, Si or Ge) or formula II or an Si- or Ge-containing soluble polymer selected from those of formulas III and IV (wherein R1-2 are each a 1-6C alkyl, a haloalkyl or a phenyl) is fed to the surface of a supporting liquid, for example, the surface of water to form an ultrathin polymer film. Such films are laminated by adhesion and heat-treated at 300-1000 deg.C. |
