  • Aromatic amide groups-containing diamines and polymers in which these diamines are incorporated
    Patent number: 4980444
    Abstract: There is provided a new class of diamines of the formula ##STR1## wherein X=NH or O, and R represents a divalent, substituted or unsubstituted organic group having at the most 20 carbon atoms.The diamines, wherein X has the meaning of an O-atom, may be converted with diacids, diacid dichlorides, aromatic carboxylic acid anhydrides or diisocyanates into poly(esteraramid) amides, poly(esteraramid) imides, or poly(esteraramid) urea or, when X stands for an --NH-group, into poly(amidaramid) amides, poly(amidaramid) imides, or poly(amidaramid) urea.The wholly or largely aromatic polyamides, polyurea or polyimides are of an iterative structure.
    Type: Grant
    Filed: June 28, 1989
    Date of Patent: December 25, 1990
    Assignee: Akzo N.V.
    Inventors: Cornelis R. H. I. de Jonge, Gerrit Hoentjen, Eduard P. Magre
