Description

芳香族ポリカルボン酸またはその反応性等価物は、二酸、三酸、四酸、または四酸を超える酸（ｈｉｇｈｅｒａｃｉｄ）（または反応性等価物）であり得る。反応生成物がモノイミドである場合、ポリカルボン酸は、少なくとも２つの酸（または等価物）の基を含有する。反応生成物がジイミドである場合、ポリカルボン酸は、少なくとも４つの酸（または等価物）の基を含有する。酸の基は、５員または６員の環状イミドが形成されるように位置している。これは、酸の基が、例えば、芳香環上で相互にオルト位であり得るか、以下にさらに詳細に説明している他の関係を有してもよい（例えば、２つのカルボニル基が、隣接する２つの炭素原子に、または、順として１つの原子によって分離される２つの炭素原子に結合してもよいが、一般に、芳香環上の互いにメタの位置には結合しない）ことを意味する。しかし、この用語は、環状イミドがそれぞれの場合に必ず形成されることが必要であると解釈されるべきではない。例えば、アミドまたはエステルは環状イミド構造を形成しないが、前駆体の酸基の同一の幾何学的関係が適用可能である。 The aromatic polycarboxylic acid or reactive equivalent thereof can be a diacid, triacid, tetraacid, or a higher acid (or reactive equivalent). When the reaction product is a monoimide, the polycarboxylic acid contains at least two acid (or equivalent) groups. When the reaction product is a diimide, the polycarboxylic acid contains at least four acid (or equivalent) groups. The acid group is positioned such that a 5- or 6-membered cyclic imide is formed. This group of the acid is, for example, or can be a cross in the ortho position on the aromatic ring, which may have a other relationships that are described in more detail below (e.g., two carbonyl groups, two adjacent carbon atoms, or, may be bonded to two carbon atoms separated by one atom as a forward, generally, the does not bind) to the position meta to each other on the aromatic ring means. However, this term should not be construed as requiring that the cyclic imide be formed in each case. For example, amides or esters do not form a cyclic imide structure, but the same geometric relationship of the precursor acid groups is applicable.
