ABSTRACT:
An aromatic heterocyclic compound and an aromatic diamino compound are allowed to separately react with a dicarboxylic acid derivative in an organic solvent, thereby synthesizing two kinds of oligomers, and these two kinds of oligomers are allowed to react with each other in an organic solvent to synthesize a block copolymer precursor, or an aromatic heterocyclic compound, an aromatic diamino compound and a dicarboxylic acid derivative are allowed to react in an organic solvent, thereby synthesizing a random copolymer precursor. The block or random copolymer precursor and a matrix polymer are dissolved in an organic solvent, then, the solvent is removed from the solution, and the resulting coagulum is heated to induce a ring-closing reaction, thereby obtaining a molecular composite material in which the copolymer is dispersed finely and homogeneously in the matrix polymer.
