  γ-戊内酯基有机电解质溶液中聚芳酰胺的合成

  摘要：

  当前用于聚芳酰胺的合成方法主要涉及使用酰胺溶剂，例如N-甲基吡咯烷酮和N，N-二甲基乙酰胺。但是，这些溶剂被怀疑具有致畸性，被欧洲委员会视为“高度关注物质”。在这里，我们提出了一种良性的替代溶剂系统：一种有机电解质溶液（OES），该溶液由γ-戊内酯（GVL）和少量离子液体1-甲基-3-辛基咪唑鎓氯化物[C 8 MIm] [Cl]组成。三个商业上相关的聚芳酰胺合成：聚p亚苯基对苯二甲酰胺（PPTA），聚米亚苯基间苯二甲酰胺（PMIA）和共聚（p-亚苯基/ 3,4'-二苯醚对苯二酰胺）（ODA / PPTA）。PMIA在含有OES成功地合成[C 8 MIM] [CL]的摩尔分数X IL = 0.043，获得的特性粘度η INH = 1.94±0.064分升克-1，与当前的工业标准和基准实验室规模的综合水平相当。反应混合物也可以直接用于聚芳酰胺纤维的湿纺，并且溶剂的所有组分可以通过一系列的蒸发和蒸馏步骤以高收率回收。可以合成ODA

• Heat-Resistant Liquid Crystalline Polymer Composition having a Low Melting Temperature

  公开（公告）日：2013-02-28

  A thermotropic liquid crystalline polymer composition capable of exhibiting both a low melting temperature and good heat resistance without the use of conventional naphthenic acids is provided. The melting temperature may, for example, range from about 250° C. to about 400° C. Even at such low melting temperatures, the present inventors have surprisingly discovered that the ratio of the deflection temperature under load (“DTUL”), a measure of short term heat resistance, to the melting temperature may remain relatively high. The specific DTUL values may range from about 200° C. to about 300° C. The ability to form a polymer composition with the properties noted above may be achieved, at least in part, by the use of an aromatic amide oligomer.
• Melt-Extruded Substrate for Use in Thermoformed Articles

  A melt-extruded substrate that can be readily thermoformed into a shaped, three-dimensional article is provided. The substrate is formed from a polymer composition that contains a thermotropic liquid crystalline polymer and a unique aromatic amide oligomer. The present inventors have discovered that the oligomer can help increase the “low shear” complex viscosity of the resulting polymer. The ability to achieve enhanced low shear viscosity values can lead to polymer compositions with an increased melt strength, which allows the resulting substrate to better maintain its shape during thermoforming without exhibiting a substantial amount of sag. Due to its relatively high degree of melt strength, the polymer composition is particularly well suited for forming thin extruded substrates for use in thermoforming processes.
• Liquid Crystalline Polymer Composition Containing a Fibrous Filler

  公开（公告）日：2013-02-28

  A polymer composition that contains a thermotropic liquid crystalline polymer, fibrous filler (e.g., glass fibers), and a flow aid is provided. The flow aid is in the form of an aromatic amide oligomer which, due to its unique nature and properties, has the ability to dramatically reduce melt viscosity with only a minimal degree of blending with the polymer. More particularly, the fibrous filler is supplied to an extruder in conjunction with the polymer and/or at a location downstream thereof so that the polymer is still in a solid or solid-like state when it initially contacts the filler. In this manner, the fibrous filler and polymer are allowed to mix together while the composition still has a relatively high melt viscosity, which helps to uniformly disperse the fibrous filler within the polymer matrix. After a certain period of time, the aromatic amide oligomer is then supplied to the extruder at a location downstream from the fibrous filler to reduce the melt viscosity of the composition.
• Melt Polymerization of Low Melt Viscosity Liquid Crystalline Polymers

  A method for forming a high molecular weight liquid crystalline polymer is provided. The method include melt polymerizing two or more precursor monomers (e.g., acetylated or non-acetylated) in the presence of an aromatic amide oligomer. The present inventors have discovered that such an oligomer can lower the melt viscosity of the viscous polymer as it is formed. The ability to lower melt viscosity in situ during melt polymerization enables the formation of high molecular weight polymers that display low melt viscosity and can still be removed from the reactor vessel without solidifying therein. This not only improves the ease of processing, but also allows molecular weights to be reached that are even higher than conventionally practical.
