  4-氨基芳基（4-取代的芳基）砜中电子取代基作用的实验和理论研究

  摘要：

  通过1 H nmr，13 C nmr和红外光谱以及半经验全价CNDO / 2计算，研究了取代基对23种具有生物活性的4-氨基芳基（4-取代的芳基）砜的电子结构的影响，有和没有硫d轨道参与。良好的线性交互相关物中的光谱数据和这些和所计算的电子电荷和哈米特σ之间发现p值。在此基础上，用电子电荷扰动来解释取代基效应，该电荷扰动从取代基线性传递到整个分子，从而桥接SO 2。包括组。实验数据和理论数据之间的一致性很好，并且趋势不取决于计算中硫d轨道的包含或排除。在C（1）SO 2 C（1'）部分中的C-1和C-1'之间存在强且线性相关的σ-π电子相互作用。因此，对于案例2类型的砜，科赫和莫菲特的π电子共轭定性模型似乎是不充分的。

• 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。
• Moulding compositions for the encapsulation of electronic components

  (D An improved thermoplastic moulding composition is provided which is particularly suited for use in the impervious void-free encapsulation on a relatively expeditious basis of an electronic component wherein the preformed electronic component is positioned in a mould cavity prior to the introduction of the moulding composition via injection moulding. The moulding composition comprises a melt processable thermotropic liquid crystalline polymer which is of a relatively low weight average molecular weight of approximately 4,000 to 25,000 (e.g. approximately 4,000 to 10,000) and which is substantially incapable of further chain growth upon heating. Uniformly dispersed within the liquid crystalline polymer is approximately 40 to 80 percent by weight (e.g. approximately 50 to 75 percent by weight) of a particulate inorganic material (preferably of silicon dioxide) which serves advantageously to decrease its volumetric coefficient of thermal expansion and advantageously to increase its thermal conductivity. In a preferred embodiment the electronic component which is encapsulated is a semiconductor device, such as a relatively delicate quad or dual-in-line integrated circuit device which is assembled onto a flat prestamped lead frame or other conductive device having a plurality of leads which extend outside the area which is encapsulated. The resulting encapsulated electronic component is well protected in spite of the relatively low molecular weight of the liquid crystalline polymer and is capable of satisfactory service for an extended period of time even if adverse environmental conditions are encountered. A rugged commonly non-burning and relatively inexpensive package is provided.

  (D) 提供了一种改进的热塑性模塑组合物，该组合物特别适用于在相对较快的基础 上对电子元件进行不透水无空隙封装，其中在通过注塑成型引入模塑组合物之 前，将预制电子元件置于模腔中。模塑组合物包括一种可熔融加工的热致性液晶聚合物，其平均分子量相对较低，约为 4,000 至 25,000 （例如约为 4,000 至 10,000），并且在加热时基本上不能再发生链增长。均匀地分散在液晶聚合物中的颗粒状无机材料（最好是二氧化硅）的重量百分比约为 40%至 80%（例如约为 50%至 75%），可降低其体积热膨胀系数并提高其热导率。在一个优选的实施方案中，被封装的电子元件是一个半导体器件，如一个相对精致的四线或双线集成电路器件，它被装配在一个扁平的预冲压引线框架或其他导电装置上，该导电装置有多条引线，这些引线延伸到被封装区域之外。尽管液晶聚合物的分子量相对较低，但封装后的电子元件仍受到很好的保护，即使遇到不利的环境条件，也能在较长的时间内提供令人满意的服务。这种封装坚固耐用，通常不会燃烧，而且成本相对较低。
