Flame-retardant halogenated copolyester and electric wire coated with the same

摘要

The present invention provides a novel flame-retardant halogenated copolyester containing a branched or crosslinked structure to an extent such that it will not impair the solubility of the copolyester in solvent to thereby reduce the lowering in the softness caused by thermal history. Therefore, this copolyester and a composition comprising the same are particularly useful as a coating material for an electric wire to be used in the vicinity of a heat source or in an environment in danger of heat buildup.
