Abstract
Rigid-rod and segmented rigid-rod polymers, methods for preparing the polymers and useful articles incorporating the polymers are provided. The polymers incorporate rigid-rod backbones with pendant solubilizing groups attached thereto for rendering the polymers soluble.
Claims29
A segmented rigid-rod polymer having the formula ##STR13## wherein ##STR14## is a rigid-rod polyphenylene segment and wherein each R.sub.1, R.sub.2, R.sub.3 and R.sub.4 on each monomer unit, independently, is H or a solubilizing side group, where at least one out of one hundred of the monomer units in the rigid-rod segments incorporates a solubilizing side group, and
- -A!.sub.m -
- are non-rigid segments, wherein n is the average number of monomer units in the rigid-rod polyphenylene segments, and wherein said rigid-rod polyphenylene segments have a number average segment length (SL.sub.n) of at least about 8, and m is 1 or greater.
