BANDED TEXTURE FORMATION IN NEMATIC SOLUTION OF POLY (1,4-BENZAMIDE) IN SULFURIC ACID

Received Date: 21 February 1992

The banded texture in films prepared from nematic poly (1,4-benzamide) (PBA)/H2SO4 solution by shearing and without shearing has been studied by using microscopy techniques. The kinetic parameters of banded texture formation γc and τb were measured for nematic solution of PBA by using parallel-plate shearing apparatus. The banded texture was also observed in randomly packed domains for nematic solution of PBA on standing without shearing. The properties of banded texture show no difference between the two samples with or without shearing.
