<p>Disclosed is a terminally modified, hyperbranched polyimide which can be efficiently complexed with an inorganic material. The terminally modified, hyperbranched polyimide can be obtained by reacting a component (a), namely tetracarboxylic acid dianhydride; a component (b), namely a mixture of a triamine and a diamine as an amine component (it may be composed of a triamine only); and a component (c), namely a compound selected from those represented by the general formulae (1-1)-(1-4) as a terminal component. H2N-X-R1 (1-1) (In the formula, X represents a direct bond or an alkylene group having 1-3 carbon atoms, and R1 represents a nitrogen-containing heterocyclic group.) H2N-X-R1 (1-2) (In the formula, X is as defined above, and R1 represents a sulfur-containing heterocyclic group or an aryl group having a thiol or thioether group in the molecule.) (1-3) (In the formula, R represents a nitrogen-containing heterocyclic group.) (1-4) (In the formula, R represents a monovalent residue.)</p> |
