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.

A copolymer comprising: (a) a rigid-rod backbone comprising a chain of at least 25 organic monomer units joined together by covalent bonds, wherein at least about 95% of the bonds are substantially parallel, wherein said backbone comprises at least two different types of monomer units; and (b) solubilizing organic groups having a molecular weight of at least about 300 attached to at least 1% of the monomer units. A polymer comprising a rigid-rod backbone comprising a chain of at least 25 organic monomer units joined together by covalent bonds wherein at least about 95% of the bonds are substantially parallel, the polymer having at least two types of monomer units, at least 1% of the monomer units having pendant solubilizing organic groups having a molecular weight of at least about 300 attached thereto and wherein at least a portion of the monomer units are selected from the group of the following formulae: [Figure] IA [Figure] IIA [Figure] IIIA [Figure] IVA [Figure] VA [Figure] VIA [Figure] VIIA [Figure] VIIIA [Figure] IXA [Figure] XA [Figure] XIA wherein R1, R2, R3, and R4 can be the same or different and are hydrogen, alkyl, aryl, alkaryl, aralkyl, alkyl or aryl amide, aryl ketone, alkoxy, polyalkeneoxy, polyphenylene oxide, polyphenylene sulfide, polyvinyl chloride, polyalkylmethacrylate, polyacrylonitrile, polyalkylvinyl ether, polyvinyl alcohol, polyvinyl acetate, perfluoroalkyl, perfluoroalkoxy, polyester, polyamide, polyimide, and poly(phenoxyphenyl ketone), provided that at least one of R1, R2, R3, and R4 is other than hydrogen, and provided that the molecular weight of at least one of R1, R2, R3, and R4 is at least 300, and wherein R5 and R6 can be the same or different and are hydrogen, alkyl, aryl, alkaryl, aralkyl, alkyl or aryl amide, aryl ketone, alkoxy, polyalkeneoxy, polyphenylene oxide, polyphenylene sulfide, polyvinyl chloride, polyalkylmethacrylate, polyacrylonitrile, polyalkylvinyl ether, polyvinyl alcohol, polyvinyl acetate, perfluoroalkyl, perfluoroalkoxy, polypolyester, polyamide, polyimide, and poly(phenoxyphenyl ketone), provided that at least one of R5 and R6 is other than hydrogen, and provided that the molecular weight of at least one of R5 and R6 is at least 300; and X is NH, O, or S. A process for the preparation of a copolymer having a rigid-rod backbone comprising a plurality of organic monomers joined together by covalent bonds wherein at least about 95% of the bonds are substantially parallel and solubilizing organic groups having a molecular weight of at least about 300 attached to at least 1% of the monomers, the process comprising polymerizing a mixture of at least 2 monomer starting materials in a solvent system wherein the monomers and the copolymer are mutually soluble.
