    • A novel class of high temperature ion-containing poly(aromatic) polymers is disclosed. They are Poly(aryl amide(nullCONHnull), sulfonyl amide (nullSO2NHnull), imide((nullCOnull)2Nnull), imidazole ((nullNHnull)(nullNnull)Cnull), oxazoles ((nullNHnull)(nullOnull)Cnull), thiazoles ((nullNHnull)(nullSnull)Cnull), amino (nullNHnull) group, ether (nullOnull), sulfide (nullSnull), sulfone (nullSO2null), or some combination of them) and they contain at least one type of ionic functional group selected from the following: (a) pendent ionic group: -Q-SO3(M), or -Q-SO2nullN(M)nullSO2nullR, or nullSO2nullN(M)nullSO2nullR (b) linking ionic group: nullSO2nullN(M)nullSO2null-Q-SO2nullN(M)nullSO2null-Q-SO2nullN(M)nullSO2-Q-wherein Q is a fluorinated alkylene or fluorinated alkoxylene group with carbon number from 1 to 12, and R is a fluorinated alkyl or fluorinated alkoxy group with carbon number from 1 to 12. M can be hydrogen H, lithium Li, sodium, Na, potassium K, and other suitable metal ions or organic bases. The new polymers can be random or blocked copolymers and can be crosslinked. The polymer can be made into polymeric membranes or composite membranes suitable for fuel cell, electrochemical applications, or selective permeable applications.
    • 公开了一类新型高温离子聚(芳族)聚合物。 它们是聚(芳基酰胺(-CONH-),磺酰基(-SO 2 NH-),酰亚胺(( - CO - )2 N - ),咪唑((-NH - )( - N = -NH - )( - O - ) - ) - 噻唑(( - NH - )( - S-)C-) - 氨基(-NH-)基团,醚(-O-),硫化物 ,砜(-SO 2 - )或它们的某种组合),并且它们含有至少一种选自以下的离子官能团:(a)侧离子基团:-Q-SO 3(M)或-Q- SO 2 -N(M)-SO 2 -R或-SO 2 -N(M)-SO 2 -R(b)连接离子基团:-SO 2 -N(M)-SO 2 -Q-SO 2 -N(M)-SO 2 - Q-SO 2 -N(M)-SO 2 -Q-其中Q是碳数为1至12的氟化亚烷基或氟化烷氧基,R为碳数为1至12的氟化烷基或氟化烷氧基 M可以是H,Li,Li,Na,Na,K,和其他合适的金属离子或有机碱。 新的聚合物可以是无规或嵌段共聚物,并且可以是交联的。 聚合物可以制成适用于燃料电池,电化学应用或选择性可渗透应用的聚合物膜或复合膜。

    • A polybenzazoleolybenzazole having a residual content of a BB-PBZ monomer of not more than 0.010 wt %, which is obtained by dehydration polymerization condensation of an AA-PBZ monomer of the formula (I) wherein Ar is a quadrivalent aromatic organic residue and X is O, S or NH, and a BB-PBZ monomer of the formula (II) W—Z—W  (II) wherein Z is an optionally substituted divalent aromatic organic residue and W is a carboxyl group or a group derived from the carboxyl group, which is reactive with —XH in the AA-PBZ monomer. Because the residual content of the BB-PBZ monomer in polybenzazole is not more than 0.010 wt %, a polybenzazole fiber having a small filament denier can be produced stably at a high speed without suffering from thread breakage during the production.
    • 通过其中Ar是四价芳族有机残基的式(I)的AA-PBZ单体和X是通过其脱水聚合缩合获得的具有不大于0.010重量%的BB-PBZ单体的残留含量的聚苯并唑聚吲哚 O,S或NH,和式(II)的BB-PBZ单体,其中Z是任选取代的二价芳族有机残基,W是羧基或衍生自羧基的基团,其与-XH的反应性 AA-PBZ单体。 由于聚吲哚中的BB-PBZ单体的残留量不大于0.010重量%,所以可以高速稳定地制造具有小丝旦数的聚吲哚纤维,而在生产过程中不会发生断线。
