Abstract
A flame-retarding polyester composition is useful for coating an electric wire, which comprises a melt-mixture of, (A) a copolyester having a halogen content of 0.5 to 30 wt. % and (B) a branched copolymer prepared by the condensation polymerization of monomers mainly comprising PA1 (a)' a component mainly comprising an aromatic dicarboxylic acid or an ester-forming derivative thereof, PA1 (b)' a component mainly comprising an aliphatic glycol or an ester-forming derivative thereof and PA1 (d) a branching compound, which contains 0.001 to 0.5 molar % (based on the total amount of the carbonyl groups of the copolyester) of said branching compound (d).
