THERMOTROPE AROMATISCHE COPOLYESTER UND COPOLYESTERAMIDE.

摘要

Thermotropic aromatic copolyesters and copolyester amides capable of being shaped, of high molecular mass.
These polymers have a structure comprising repeat units of formulae (I), (II), (III), and (IV),
(I) denoting:

- with A denoting an oxygen atom or the NH group, and they have a flow temperature ranging from 200 to 350 DEG C.
These polymers make it possible to obtain moulded objects, filaments and films endowed with good mechanical properties.
