ABSTRACT:
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.
