The present invention relates to a poly(amic acid) obtained from monomer components comprising a tetracarboxylic acid component and a diamine component. The poly(amic acid) is characterized in that the monomer components contain not less than 25 mol.% of at least one component selected from among the group consisting of a tetracarboxylic acid dianhydride having a 9,9'-diphenylfluorene structure and a diamine having a 9,9'-diphenylfluorene structure, and contain not less than 25 mol.% of at least one component selected from among the group consisting of an amide bond-containing tetracarboxylic acid dianhydride, an alicyclic tetracarboxylic acid dianhydride, an alicyclic diamine, a fluorine atom-containing tetracarboxylic acid dianhydride, a fluorine atom-containing diamine, a sulfur atom-containing tetracarboxylic acid dianhydride, a sulfur atom-containing diamine, a silicon atom-containing tetracarboxylic acid dianhydride and a silicon atom-containing diamine. La présente invention concerne un poly(acide amique) obtenu à partir de constituants monomères comprenant un constituant acide tétracarboxylique et un constituant diamine. Le poly(acide amique) est caractérisé en ce que les constituants monomères ne contiennent pas moins de 25 % en moles d'au moins un constituant choisi dans le groupe constitué par un dianhydride d'acide tétracarboxylique ayant une structure 9,9'-diphénylfluorène et une diamine ayant une structure 9,9'-diphénylfluorène, et ne contiennent pas moins de 25 % en moles d'au moins un constituant choisi dans le groupe constitué par un dianhydride d'acide tétracarboxylique contenant une liaison amide, un dianhydride d'acide tétracarboxylique alicyclique, une diamine alicyclique, un dianhydride d'acide tétracarboxylique contenant un atome de fluor, une diamine contenant un atome de fluor, un dianhydride d'acide tétracarboxylique contenant un atome de soufre, une diamine contenant un atome de soufre, un dianhydride d'acide tétracarboxylique contenant un atome de silicium et une diamine contenant un atome de silicium.
