Abstract
The formation processes of structure in 12% solutions of poly(p-phenyl ene)pyromellitamido acid in DMAA that take place upon storage for a mo nth at room temperature and for a year at 2 degrees C were quantitativ ely studied by polarized light scattering. The structural rearrangemen ts were reversible and heating for 15 min at 50 degrees C restored the initial structure of the system.
