摘要： A cationic-dyeable polyamide, polymerized from omega aminocarboxylic acids or their lactams, of improved physical properties can be made by using from 0.25 to 0.85 mole percent (based on the polyamide) of the sodium salt of a sulfonated dicarboxylic acid such as 5-sulfoisophthalic acid and 0.07 to 0.65 mole percent of an N-sulfoalkyl alkyldiamine such as N-(4sulfobutyl)hexamethylenediamine, or N-(2-sulfoethyl)mxylylenediamine. A polyamide results containing the respectively same number of sulfo groups, but with less diluent and consequently having a higher melting point. The diacid can be a sulfonate derivative of a phthalic acid, or of fluorene, etc. The diamine can be a sulfonate derivative of hexamethylenediamine, metaxylylenediamine, etc. The use of the combination of additives eliminates the necessity of adding a diamine or dicarboxylic acid to achieve full polymerization.

摘要： It has been suggested that a high strength polycaproamide fiber having excess number of carboxyl end groups over amino end groups can be produced by melt spinning a polymer prepared by polymerizing e-caprolactam and reacting the polymer with a dibasic carboxylic acid containing at least six carbon atoms. However, with incorporation of this dicarboxylic acid reactant in continuous operation, serious problems have been encountered in melt-spinning of the polymer due to the frequent occurrence of ''''nubs'''' or enlarged places in the extruded polyamide filament. It has now been found that the occurrence of said nubs in the fiber can be greatly reduced by utilizing certain polyanhydrides of dicarboxylic acid and reacting the polyanhydride at the end of the polymerization. Moreover, dyeing properties of the fiber may be more readily controlled.
摘要翻译：已经提出，在氨基端基上具有过量羧基端基的高强度聚己酰胺纤维可以通过将通过聚合ε-己内酰胺制备的聚合物熔融纺丝并使聚合物与含有至少6个碳原子的二元羧酸反应来制备。然而，通过在连续操作中引入这种二羧酸反应物，由于在挤出的聚酰胺长丝中频繁出现“重叠”或扩大的位置，聚合物的熔融纺丝已经遇到严重的问题。现在已经发现，通过使用某些二羧酸的聚酐并且在聚合结束时使聚酐反应，可以大大降低纤维中所述核子的出现。此外，可以更容易地控制纤维的染色性。
