Thermotropic polyester amides

Melt processable fibre-forming polyesteramides comprising residues of one or more aminophenols selected from p-aminophenol and p-N-methylaminophenol and residues of one or more dicarboxylic acids characterized in that the polyesteramide contains a balance of linear difunctional residues and dissymme...

Beschreibung
Zusammenfassung:	Melt processable fibre-forming polyesteramides comprising residues of one or more aminophenols selected from p-aminophenol and p-N-methylaminophenol and residues of one or more dicarboxylic acids characterized in that the polyesteramide contains a balance of linear difunctional residues and dissymmetric difunctional residues derived from either the aminophenols or the acids chosen to give a product which melts below its decomposition temperature and exhibits optical anisotropy in the melt.
