Abstract:
(EN) Polymeric alloys of rod-like and coil-like aromatic heterocyclic polymers useful for the fabrication of high strength load bearing structural components. In one aspect of the invention, rod-like aromatic heterocyclic polymers are used as reinforcement in coil-like heterocyclic polymer matrices to provide composites at the molecular level that are analogous to chopped fiber composites. A representative example of the coil-like heterocyclic polymer consists essentially of repeating units having the following structural formulas: (FORMULA) wherein X is NR No, O or S, where o is phenyl, Ar" in (FORMULA) or (Alpha) and m is an integer having a value such that the polymer has an intrinsic viscosity of about 2 to 20 dl/g as determined in methanesulfonic acid at 30 C, and a representative example of the rod-like aromatic heterocyclic polymer consists essentially of repeating units having the following structural formulas: (FORMULA) wherein X is NR, No, O or S, where o is phenyl, Ar is (Alpha) or (Alpha) and n is an integer having a value such that the polymer has an intrinsic viscosity of about 5 to 30 dl/g as determined in methanesulfonic acid at 30 C.
(FR) Alliages de polymeres heterocycliques aromatiques en barres ou en spirales utiles a la fabrication d"elements de structure a haute resistance. Dans un aspect de l"invention, des polymeres heterocycliques aromatiques en barres sont utilises en tant que renforcement dans des matrices polymeres heterocycliques en spirale pour obtenir des composites au niveau moleculaire qui soient analogues aux composites de fibres coupees. Un exemple representatif de polymere heterocyclique en spirale consiste essentiellement a repeter des motifs ayant les formules suivantes: (FORMULE) ou X est NR, No, O ou S, ou o est le phenyl, Ar" dans (FORMULE) ou (Alpha) et m est un nombre entier ayant une valeur telle que le polymere possede une viscosite intrinseque d"environ 2 a 20 dl/g determinee dans l"acide methanesulfonique a 30 C, et un exemple representatif d"un polymere heterocyclique aromatique en barres consiste essentiellement en une repetition de motifs ayant les formule suivantes: (FORMULE) ou X est NR, No, O ou S, ou o est le phenyle, Ar est (Alpha) ou (Alpha) et n est un nombre entier ayant une valeur telle que le polymere possede une viscosite intrinseque d"environ 5 a 30 dl/g determinee dans l"acide methanesulfonique a 30 C.
