Synthesis and characterization of organosoluble copolyimides based on 2,2-Bis[4-(4-aminophenoxy)phenyl]propane, 2,2-Bis[4-(4-aminophenoxy)phenyl]hexafluoropropane and a pair of commercial aromatic dianhydrides

Organosoluble homopolyimides (PIs) and copolyimides (CoPIs) were synthesized from 2,2-bis[4-(4-aminophenoxy)phenyl]propane (BAPP) or 2,2-bis[4-(4-aminophenoxy)phenyl]hexafluoropropane (6FBAPP) and six kinds of commercial aromatic dianhydrides (PMDA, IIa ; BTDA, IIb ; BPDA, IIc ; ODPA, IId ; DSDA, IIe ; 6FDA, IIf ). Although BAPP and IId∼f could prepare three kinds of soluble PIs (III-Ad∼f ), likewise 6FBAPP and IIc∼f could prepare four PIs (III-Bc∼f ), the insoluble PIs were synthesized from these two diamines and other dianhydrides. However, soluble CoPIs could be prepared by alternative copolycondensation from a pair of dianhydrides of soluble PIs and insoluble PIs in certain molar ratios (m1/m2). The ratios of m1/m2 of BAPP/PMDA series CoPIs (IVm1(d–f)/m2a ) ranged from 3–5, but ratios of 6FBAPP/PMDA series CoPIs (Vm1(c∼f)/m2a ) decreased to 2–3. The m1/m2 of the BAPP/BTDA and 6FBAPP/BTDA series CoPIs were 2, while the BAPP/BPDA series were between 1–2. Composition, solubility, tensile properties and thermal properties of these CoPIs synthesized via a two-stage thermal cyclodehydration were determined and were compared with their corresponding PIs. © 2000 John Wiley & Sons, Inc.

基于 2,2-双[4-(4-氨基苯氧基)苯基]丙烷、2,2-双[4-(4-氨基苯氧基)苯基]六氟丙烷和一对商业芳族二酐的有机可溶性共聚酰亚胺的合成和表征

有机可溶性均聚酰亚胺 (PIs) 和共聚酰亚胺 (CoPIs) 由 2,2-双[4-(4-氨基苯氧基)苯基]丙烷 (BAPP) 或 2,2-双[4-(4-氨基苯氧基)苯基]六氟丙烷合成 ( 6FBAPP)和六种商业芳族二酐(PMDA,IIa;BTDA,IIb;BPDA,IIc;ODPA,IId;DSDA,IIe;6FDA,IIf)。虽然 BAPP 和 IId∼f 可以制备三种可溶性 PIs (III-Ad∼f ),但同样 6FBAPP 和 IIc∼f 可以制备四种 PIs (III-Bc∼f ),不溶性 PIs 是由这两种二胺和其他二酐。然而,可溶性 CoPI 可以通过可溶性 PI 和不溶性 PI 以一定摩尔比 (m1/m2) 的一对二酐进行交替共缩聚来制备。BAPP/PMDA 系列 CoPI 的 m1/m2 比值 (IVm1(d–f)/m2a ) 范围为 3–5,但 6FBAPP/PMDA 系列 CoPI (Vm1(c∼f)/m2a ) 的比率下降到 2-3。BAPP/BTDA 和 6FBAPP/BTDA 系列 CoPI 的 m1/m2 为 2,而 BAPP/BPDA 系列在 1-2 之间。测定了通过两阶段热环脱水合成的这些 CoPI 的组成、溶解度、拉伸性能和热性能,并与它们相应的 PI 进行了比较。© 2000 John Wiley & Sons, Inc.
