Solution Processing - Rodlike Polymers

Abstract

The solution processing of polybenzoxazole (PBO) and polybenzthiozole (PBT) to form oriented solids is discussed. The rheological considerations important in solution processing are considered, with special emphasis on the dry-jet wet spinning process used to form fibers. Pertinent rheological time constants and orientation parameters are measured by cone-and-plate rheometry and parallel plate flow birefringence. Solution processing experiments to evaluate the proposed process models are presented, along with evaluation of the properties of the formed solid polymers.
