Thermotropic copolyazomethines having a mesophase temperature range lying within a desired range of values are obtained by copolymerizing terephthalic aldehyde with at least two different 1,n-bis(4-aminophenoxy)alkanes. Such copolyazomethines are particularly useful as reinforcing materials for the usual thermoplastic polymers, such as polycarbonate, polybutyleneterephthalate, polyethyleneterephthalate and polyamides.
通过共聚合对苯二醛和至少两种不同的1,n-双(4-
氨基苯氧)烷,可以获得具有所需温度范围内的介向温度范围的热致变性共聚物。这种共聚物特别适用于通常的热塑性聚合物,如聚
碳酸酯、聚
对苯二甲酸丁二酯、聚
对苯二甲酸乙二酯和聚酰胺的增强材料。
