| abstract |
The present invention relates to high molecular weight conformable thermotropic aromatic copolyesters.n n n These copolyesters have a structure comprising the recurrence units of formulas (I), optionally (II), (III). And (IV), (I) denoting: with R, which can be a methyl and / or ethyl radical and / or a chlorine atom and / or a bromine atom, (II) denoting: (III) designating: and (IV) designating: and they have a temperature flow rates from 200 to 350 ° C.n n n These copolyesters make it possible to obtain molded objects, wires and films endowed with good mechanical properties. |
