Patent

CA 2200704

An aramid composition consisting essentially of repeat units derived from p- phenylenediamine, terephthalic acid, 3,3'-bibenzoic acid, and optionally chloroterephthalic acid, is disclosed. The aramids are especially useful for fibers, which after drawing usually have enhanced tensile moduli and strengths, which makes them especially useful in ropes and cables, and in composites.

L'invention a pour objet une composition d'aramide constituée essentiellement d'unités de répétition dérivées de p-phénylènediamine, d'acide téréphtalique, d'acide 3,3'-bibenzoïque et éventuellement d'acide chlorotéréphtalique. Les aramides sont particulièrement utiles pour les fibres qui, après étirage, présentent généralement des modules et des résistances à la traction supérieurs, ce qui permet de les utiliser dans des cordes et des câbles, ainsi que dans des composites.
