Aromatic-aliphatic diamines of the formula ##STR1## in which Ar is an arylene or substituted arylene are useful in preparing thermally stable, rigid, polyamides, polyureas and polyurethanes having a repeating unit of the formula ##STR2## in which Ar is arylene or substituted arylene, X is --NH-- or --O--, n is 0 or 1, and R is a divalent organic radical. Polymers of this invention can be melt-spun into thermally stable fibers.
式为##STR1##的芳香-脂肪族二胺,其中Ar是芳基或取代芳基,可用于制备具有重复单元式##STR2##的热稳定、硬性聚酰胺、聚氨酯和聚氨醚,其中Ar是芳基或取代芳基,X是--NH--或--O--,n为0或1,R为二价有机基团。本发明的聚合物可熔融纺成热稳定纤维。
