Abstract

The current state of understanding of the morphology of the rigid-rod polymers PBZT and PBZO is reviewed. The morphology is sensitive to both the structure of the rigid polymer molecules and the nature of processing. Structural models of fiber morphology consistent with experiment are presented. An extensive bibliography is included.
