Process for improving the chemical resistance of aromatic polyesters |
| abstract |
Provess for improving the chemical resistance of copolyesters derived from aromatic dicarboxylic acids, certain substituted aromatic diols and, optionally, aromatic hydroxy acids. The process involves treating shaped objects made from the aromatic polyesters by subjecting them to a temperature sufficient to raise the surface temperature thereof to at least 275 DEG C. and preferably 300 DEG C. in air or other oxygen-containing atmospheres. |
