CA 2001716

High-performance polymers having a rigid-rod backbone comprising a chain length of at least 25 organic monomer units joined together by covalent bonds wherein at least about 95% of the bonds are substantially parallel; and solubilizing organic groups attached to at least 1% of the monomer units. The polymers are prepared in a solvent system which is a solvent for both the monomer starting materials and the rigid-rod polymer product.

Polymères à haut rendement, possédant un squelette droit rigide, avec une chaîne d'au moins 25 unités monomères organiques, reliées par des liaisons covalentes; au moins 95 % des liaisons sont pratiquement parallèles, et au moins 1 % des unités monomères sont liées à des groupes organiques solubilisants. Les polymères sont préparés dans un système qui est un solvant aussi bien pour le monomère de départ que pour le polymère droit rigide.
