• METHOD FOR PREPARING QUATERNARY PHOSPHONIUM SALTS

  A two-step pathway for preparing high pure quaternary phosphonium salts is disclosed. In the first step, hydrogen phosphide (PH 3 ) or a higher phophine reacts with a protonic compound to produce a phosphonium salt, which then reacts with a carbonic acid diester to produce a quaternary phosphonium salt in the second step. On one hand, hydrogen phosphide (PH 3 ) and higher phophines, including primary phosphines, secondary phosphines, and tertiary phosphines, after neutralization with protonic compound, become sufficiently reactive and can be alkylated by carbonic acid diester to form quaternary phosphonium cations. On the other hand, as an anion-exchange procedure is completely avoided, the process not only gives quaternary phosphonium salts of high purity, but also gives people freedom to design the cation and the anion of a quaternary phosphonium salt synchronously by choosing a preferred phosphine and a protonic compound that can supply a desired anion.

  揭示了一种制备高纯度四元磷铵盐的两步途径。在第一步中，氢磷化物（PH3）或更高的磷化物与质子化合物发生反应，产生磷铵盐，然后在第二步中与碳酸二酯发生反应，产生四元磷铵盐。一方面，氢磷化物（PH3）和更高的磷化物，包括一次磷化物、二次磷化物和三次磷化物，在与质子化合物中和后变得足够活性，可以被碳酸二酯烷基化形成四元磷铵阳离子。另一方面，由于完全避免了阴离子交换程序，该过程不仅提供高纯度的四元磷铵盐，还使人们可以通过选择理想的磷化物和可以提供所需阴离子的质子化合物，同时设计四元磷铵盐的阳离子和阴离子。

• Improved process for forming thermally stable thermotropic liquid crystalline polyesters of predetermined chain length

  An improved polymerisation process is provided for the formation of a polyester which is capable of forming an anisotropic melt phase and which optionally may include amide linkages. An approximately 0.4 to 3 percent molar excess of aromatic dicarboxylic acid monomer (e.g. terephthalic acid) and/or an esterified derivative thereof is provided in the polymerisation zone during the polymerisation reaction. Such monomer imparts dicarboxyaryl units to the interior of the resulting polymer chains and causes the polymer chains to terminate in carboxylic acid end groups and/or an esterified derivative thereof wherein the polymer chains achieve a predetermined average chain lengththrough the depletion of other monomers present in the polymerisation zone. The resulting polyester unlike the usual product of the prior art is substantially incapable of additional chain growth upon subsequent heating and accordingly may be relied upon to maintain a substantially constant viscosity during melt processing regardless of the duration of heating.

  本发明提供了一种改进的聚合工艺，用于形成一种可形成各向异性熔体相的聚酯，该聚酯可选择性地包括酰胺连接。在聚合反应过程中，在聚合区中加入约 0.4%至 3%摩尔过量的芳香族二羧酸单体（如对苯二甲酸）和/或其酯化衍生物。这种单体将二羧基芳基单元赋予所产生的聚合物链的内部，并使聚合物链以羧酸末端基团和/或其酯化衍生物终止，其中聚合物链通过耗尽聚合区中存在的其他单体而达到预定的平均链长。由此产生的聚酯与现有技术中的普通产品不同，在后续加热过程中基本上不会产生额外的链增长，因此在熔融加工过程中，无论加热时间长短，都能保持基本恒定的粘度。
