Phase side group coil systems

Phase Diagram for Side Group Liquid Crystal-Coil Systems... [Pg.83]

The study of phase transitions for PBG-solvent systems is facilitated by the fact that despite the rigid-chain character of this pmlymer, its solubility in the coiled state is high due to the interaction (solvation) of the side groups with the solvent molecules. The situation is more complex for another group of rigid-chain linear polymers aromatic pwlyamides with p-phenylene units. These px)lymers are soluble in a limited group of solvents in particular, px)ly-p-benzamide dissolves in dimethyl acetamide (DMAA) only when lithium chloride is added, while poly-p-phenylene terephthalamide only goes into solution in some concentrated acids. [Pg.51]
