    摘要: This invention discloses high-temperature adhesives having a good light-transmittance and excellent high-temperature flowability which comprises polyimide having recurring units represented by the following formula (I)
    (where R is a tetra-valent radical selected from the group consisting of aliphatic radical having not less than two carbons, cyclo-aliphatic radical, monoaromatic radical, condensed polyaromatic radical, and non condensed polyaromatic radical wherein aromatic radicals are mutally connected with a bond or a crosslinking function). The ployimide is obtained by preparing polyamic acid through the reaction of 2,2-bis[4-(3-aminophenoxy)phenyl]-1,1,1,3,3,3,-­hexafluoropropane as a diamine component with tetracarboxylic dianhydride such as pyromellitic dianhydride, 3,3ʹ,4,4ʹ-­biphenyltetracarboxylic dianhydride, bis(3,4-dicarboxyphenyl) ether dianhydride and 3,3ʹ4,4ʹ-benzophenonetetracarboxylic dianhydride, and further conducting the ring-closing reaction of resultant polyamic acid by dehydration.

    摘要: Polyimide having repeating units of the following formula (I) and its polyamic acid precursor having repeating units of the following formula (II) are disclosed;
    (where Y is a radical selected from the group consisting of a bond, divalent hydrocarbon having 1 to 10 carbons, hexafluorinated isopropylidene, carbonyl, thio, sulfinyl, sulfonyl and oxide, and R is a tetra-valent radical selected from the group consisting of aliphatic radical having 2 and more carbons, cyclo-aliphatic radical, monoaromatic radical, condensed polyaromatic radical, and non-condensed polyaromatic radical wherein aromatic radicals are mutually connected with a bond or a crosslinking function).
    Typical examples of polyimide and polyamic acid include where
    Y is thio radical and R is
    Y is a bond and R is III or IV, and Y is isopropylidene radical and R is IV.
    The polymers can be prepared from corresponding diamine and tetracarboxylic acid dianhydride.
    Polyimide or polyamic acid of this invention is excellent for high-temperature adhesive.
