Abstract:
1. A terminally-modified polybranched polyimide obtained by reacting: component (a): tetracarboxylic dianhydride: component (b): as an amine component, a mixture of a triamine and a diamine, wherein the mixture may be composed of a triamine only; and component (c): as a terminal component, a compound selected from general formulae (1-1) to (1-4); such that at least a part of polymer terminal is derived from the compound selected from the general formulae (1-1) to (1-4); wherein, in the general formula (1-1), X represents a single bond or an alkylene group having 1 to 3 carbon atoms; R wherein, in the general formula (1-2), X represents a single bond or an alkylene group having 1 to 3 carbon atoms; R wherein, in the general formula (1-3), R represents a nitrogen-containing heterocyclic group substituted with any group selected from the substituent group α; wherein the substituent group α is as defined in the general formula (1-1); wherein, in the general formula (1-4), R each represents a monovalent residue and have the same meaning as the substituent group α defined in the general formula (1-1); and R may be the same or different each other.
