摘要： Methods of making AF4 using novel reducing agents that result in reduced cost. Low dilution technology may be used to provide AF4 in substantially improved yields. The relative amount of transition metal catalyst can be decreased. The amount of undesired byproduct is also reduced.

摘要翻译： 使用导致降低成本的小说制备聚对二甲苯AF4的方法。 低稀释技术可用于以显着提高的产率提供聚对二甲苯AF4。 过渡金属催化剂的相对量可以降低。 不希望的副产物的量也减少了。
