Abstract
This paper reported the phase diagrams of PBZT (poly-1,4-phenylene benzobisthiazole)/nylon/MSA, PBZT/poly(sodium 2-acrylamido-2 methylpropane sulfonate) NaAMPS)/MSA, PBZT/2-acrylamido-2 methylpropane sulfonic acid (HAMPS)/MAS, and PBZT/poly (p-phenyleneterephthalamido) propanesulfonate)( PPTA-PS)/MSA. The ternary phase diagram of rigid rod polymer PBZT and amorphous nylon in methanesulfonic acid (MSA) solvent was found to follow Flory's prediction of a rod/coil/solvent ternary system very well. When sulfonated polymers, such as NaAMPS polymer and PPTA-PS, were used instead of nylon in a ternary solution, it was found that the phase behavior deviated from Flory's theory due to the possible coil/rod intermolecular interaction in the ternary solution. It was found that for the PBZT/nylon/MSA system, the X3 value was consistent with the contour length of the coil molecules as predicted by Flory's theory. However, both PBZT/HAMPS-monomer/MSA and PBZT/NaAMPS polymer/MSA systems showed an X3 value of unity. The ternary phase diagram of PPTA-PS system shows an X3 value larger than 1, which indicates the ionic interaction is not perfect like PBZT/NaAPMS polymer/MSA and PBZT/HAMPS monomer/MSA system. This suggests that the degree of intermolecular interaction between rod and coil plays an important role in determining the phase behavior of rod/coil/solvent ternary system.
