A soluble rigid-rod macromonomer is provided which has the following formula: [ STR 1 ] wherein each G.sub.1, G.sub.2, G.sub.3, and G.sub.4, on each monomer unit, independently, is H or a solubilizing side group, provided that at least one monomer unit has at least one solubilizing side group. The s
A soluble rigid-rod macromonomer is provided which has the following formula: [ STR 1 ] wherein each G.sub.1, G.sub.2, G.sub.3, and G.sub.4, on each monomer unit, independently, is H or a solubilizing side group, provided that at least one monomer unit has at least one solubilizing side group. The solubilizing side groups provide the macromonomers with a solubility of at least 0.5% by weight in the solvent system from which they are formed. E is a reactive end group, and the macromonomer has an average degree of polymerization, DP.sub.n, greater than 6. Such macromonomers are chemically incorporated into polymer systems to provide stronger stiffened polymers.

[ What is claimed is:] [1.] A soluble rigid-rod macromonomer of the formula: [ STR 27 ] wherein each G.sub.1, G.sub.2, G.sub.3, and G.sub.4, on each monomer unit, independently, is H or a solubilizing side group, provided that at least one monomer unit has at least one solubilizing side group, where
[ What is claimed is:] [1.] A soluble rigid-rod macromonomer of the formula: [ STR 27 ] wherein each G.sub.1, G.sub.2, G.sub.3, and G.sub.4, on each monomer unit, independently, is H or a solubilizing side group, provided that at least one monomer unit has at least one solubilizing side group, wherein said solubilizing side groups provide said macromonomers with a solubility of at least 0.5% by weight in the solvent system from which they are formed, and wherein said solubilizing side groups G are selected from the group consisting of phenyl, biphenyl, naphthyl, phenanthryl, anthracenyl, benzyl, benzoyl, naphthoyl, phenoxy, phenoxyphenyl, phenoxybenzoyl, alkyl, alkyl ketone, aryl, aryl ketone, aralkyl, alkaryl, alkoxy, aryloxy, alkyl ester, aryl ester, amide, alkyl amide, dialkyl amide, aryl amide, diaryl amide, alkyl aryl amide, amides of cyclic amines such as piperidine, piperazine and morpholine, alkyl ether, aryl ether, alkyl sulfides, aryl sulfides, alkyl sulfones, aryl sulfones, thioether, fluoro, trifluoromethyl, perfluoroalkyl, and pyridyl, where alkyl is a linear or branched hydrocarbon chain having between 1 and 30 carbon atoms, and aryl is any single, multiple or fused ring aromatic or heteroaromatic group having between 3 and 30 carbon atoms, and fluorine-substituted analogs of the aforementioned G groups; E is a reactive end group selected from the group consisting of acetals, acetylenes, acetyls, acid anhydrides, acrylamides, acrylates, aldehydes, alkyl aldehydes, amines, amides, anilines, aryl aldehydes, azides, benzocyclobutenes, biphenylenes, carboxylates, carboxylic anhydrides, cyanates, cyanides, epoxides, esters, ethers, formyls, fulvenes, heteroaryls, hydrazides, hydroxylamines, imides, imines, isocyanates, ketals, ketoalkyls, ketoaryls, ketones, maleimides, nadimides, nitrites, olefins, phenols, phosphates, phosphonates, silanes, silicates, silicones, silyl ethers, styrenes, sulfonamides, sulfones, sulfonic acids and their salts, sulfoxides, tetrahydropyranyl ethers, urethanes, vinyl ethers, thioethers, and vinyls; the macromonomer has an average degree of polymerization, DP.sub.n, greater than 6; and adjacent monomer units are oriented head-to-head, head-to-tail, or randomly.
