    摘要: A linear aromatic polyester comprising, in the polymer molecule, at least 50 mole % of a repeating unit being represented by the formula ##SPC1##In whichR.sub.1 and R.sub.2 are the same or different and represent an alkyl group of 1-3 carbons, n is an integer of 1-6, X is a halogen atom and m is 0, 1 or 2,With an intrinsic viscosity of 0.3 or more when measured at 35.degree.C. by use of orthochlorophenol as a solvent.
