Aromatic polyether-esters were synthesized from hydroxy acid-type monomers, in order to obtain melt-processable, crystalline aromatic polymers. Poly (oxy-1, 4-phenyleneoxy-1, 3-phenylenecarbonyl) had a melting temperature of 292°C and poly (oxy-1, 4-phenyleneoxy-1, 4-phenyleneoxy-1, 4-phenylenecarbonyl) had those of 307, 326°C (double peaks). Both polymers could be melt-spun to yield fibers having moderate tensile properties and fairly good heat durability at 220°C.
