  Polyimides consisting of PMDA and an aromatic diamine are normally solvent-insoluble. According to the present invention, they are solubilized in solvents to prepare four-component or higher block copolymers containing BTDA. PMDA is reacted with a certain type of aromatic diamine in a molar ratio of 1:2-1.5 to produce a solvent-soluble oligomer. This is combined with an acid dianhydride and an aromatic diamine to produce a four-component or higher solvent-soluble block copolymer. The molar ratio of the aromatic diamine added with PMDA is 1:2-1.5. A number of solvent-soluble block copolymers containing PMDA can be prepared. Four-component or higher polyimide block copolymers containing PMDA, BTDA, and DAT are prepared by sequential reactions in the presence of a binary catalyst. This made it possible to prepare various polyimides from many inexpensively available materials. Polyimides containing PMDA-BTDA-DAT can be prepared at high performance, in mass and at low cost by using economical direct imidation, and therefore can be widely used in future.

  由 PMDA 和芳香族二胺组成的聚酰亚胺通常不溶于溶剂。根据本发明，可将它们溶解在溶剂中，制备含有 BTDA 的四组份或更高组份嵌段共聚物。PMDA 与某种芳香族二胺以 1:2-1.5 的摩尔比进行反应，生成可溶于溶剂的低聚物。低聚物与酸性二酐和芳香族二胺反应生成四组份或更高组份的可溶于溶剂的嵌段共聚物。 芳香族二胺与 PMDA 的摩尔比为 1:2-1.5。可以制备多种含有 PMDA 的溶剂可溶嵌段共聚物。 在二元催化剂存在下，通过连续反应可制备出含有 PMDA、BTDA 和 DAT 的四组份或更高组份的聚酰亚胺嵌段共聚物。这使得利用许多廉价材料制备各种聚酰亚胺成为可能。含有 PMDA-BTDA-DAT 的聚酰亚胺可通过经济的直接酰亚胺法制备出高性能、大规模和低成本的聚酰亚胺，因此可在未来得到广泛应用。
