Abstract
Abstract A halogen-containing polyester resin composition characterised in that it comprises a flame-retardant aromatic polyester copolymer having a halogen content of 0.5 to 30% of weight which is produced by condensation polymerization reaction of (A) principally an aromatic dicarboxylic acid or an ester-forming derivative thereof, (B) principally an aliphatic glycol or an ester-forming derivative thereof, and (C) an ester-forming compound containing a halogen, and, in mixture therewith, 0.1 to 10% by weight of a bisoxazoline compound relative to the total weight of the composition. The invention also extends to an electric conductor wire heating its surface covered with a covering material characterised in that the covering material is comprised of the above defined halogen containing polyester resin composition.
