<p>High-performance polymers having a rigid-rod backbone comprising a chain length of at least 25 monomer units joined together by covalent bonds wherein at least about 95 % of the bonds are substantially parallel; and solubilizing organic groups having an average molecular weight of at least about 300 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.</p> |
