The syntheses and characterizations of poly(oxy(2-methyl-1,3-phenylene)-oxyisophthaloyl-b-oxy(2-methyl-1,3-phenylene)oxyterephthaloyl) and the corresponding homopolymers are described. The synthesis involved the coupling of dihydroxy-terminated homopolymers with terephthaloyl chloride. The resulting block copolyester was characterized by infrared spectroscopy, proton and carbon-13 nuclear magnetic resonance spectroscopy, solution viscosity, differential scanning calorimetry, and thermogravimetric analysis.
