• Phosphate salts of monomers for PBZ and their use in preparing PBZ polymers

  PBZ polymers are synthesized by the reaction of AA- and BB-monomers. The BB-monomer is conveniently synthesized and isolated as a phosphate salt having a uniform number of phosphate ions associated with each BB-monomer ion. Such high purity monophosphate and diphosphate salts can be obtained by precipitating the monomer from an aqueous acid solution by adjusting the pH balance or from a mixture of phosphoric acid and a volatile, polar, saturated organic liquid at a rela­tively low temperature.

  PBZ 聚合物是通过 AA 和 BB 单体反应合成的。BB 单体可方便地合成和分离为磷酸盐，这种磷酸盐具有与每个 BB 单体离子相关联的均匀数量的磷酸根离子。这种高纯度的单磷酸盐和二磷酸盐可通过调节 pH 值平衡从酸性水溶液中沉淀单体，或在相对较低的温度下从磷酸和挥发性、极性、饱和有机液体的混合物中沉淀单体而获得。

  It is advantageous to prepare oligomers of polybenzazole polymers by reaction of AA-PBZ monomer with an excess of BB-PBZ monomer. The resulting oligomer dopes may be stored at a temperature at which they remain pumpable until such time as the dope can be advanced to higher molecular weight by adding additional AA-PBZ monomer. The molecular weight of the polymer may be adjusted by controlling the amount of chain extender and/or chain terminator added to oligomer mixtures as they are advanced to final molecular weight.

  通过 AA-PBZ 单体与过量的 BB-PBZ 单体反应制备聚苯唑聚合物的低聚物是非常有利的。得到的低聚物掺合料可以储存在一定的温度下，在加入额外的 AA-PBZ 单体使掺合料达到更高的分子量之前，它们仍然是可泵送的。聚合物的分子量可以通过控制添加到低聚物混合物中的扩链剂和/或链终止剂的量来调整，因为它们会被提升到最终分子量。

  A method for sulfonating fibers or films comprising polybenzazole polymers is described. These sulfonated polybenzazole fibers are incorporated into composites containing a matrix resin such as an epoxy resin. The interfacial shear strength of these sulfonated polybenzazole fiber-containing composites is significantly improved over the interfacial shear strength of similar composites containing unsulfonated polybenzazole fibers.
