Positive and negative photostructures are formed after the polyimide (PI) of 4,4′-biphthalic anhydride (BPA) and 4,4′-diamino-3,3′-dimethyldiphenylmethane (DADMDPM), PI(BPA/DADMDPM) is doped with Michler′s ketone (MK) and benzophenone (BP), r

Four kinds of benzophenone-containing polyimides, each of which carries different amount or distribution of methylthiomethyl (MTM) pendant groups, are applied as negative photoresists. Lithographic evaluation of these polyimides shows that PI-42, the

Some methylthiomethyl (MTM)-pendant polyimides were allowed to react with bivalent ions of Ni, Zn, Cd and Hg. The values for metal ion uptake for these polyimides followed the order Hg(II) > Cd(II) > Zn(II) > Ni(II). The selective chelating behaviour

A series of novel polyimides are synthesized by the reaction of 3,3′,4,4′-benzophenonete-tracarboxylic dianhydride (BTDA) with four methylthiomethyl-substituted aromatic diamines: 3-methylthiomethyl-4,4′-diaminodiphenylmethane (I), 3,3′-dimet

Procedures are described to convert 4,4′-diaminodiphenylmethane into its ortho-(methylthiomethyl) derivatives. Mechanism for formation of ortho-dialkylated products is discussed and generalizations for dialkylation are founded.
