    摘要: A process for producing a polyimide precursor having excellent adhesion property and improved moisture resistance by polymerization of an organic tetracarboxylic acid component and a diamine is disclosed. A portion of the organic tetracarboxylic acid is reacted with an aminosilane compound in which H in an amino group is substituted with a monovalent organic group containing a hydrophobic aromatic ring, to produce a silane-modified polycarboxylic acid component and the resulting silane-modified polycarboxylic acid component is polymerized with a diamine together with the residual organic tetracarboxylic acid component.
