Rare earth (Nd, Y, La, Dy) stearates have been synthesized and used as single component catalysts for the polycondensation of dimethyl terephthalate, adipic acid and 1,4‐butanediol for the first time preparing biodegradable poly(butylene adipate‐ co ‐terephthalate) (PBAT) with high molecular weight. The microstructures of PBAT were characterized by 1 H NMR spectra. The PBAT exhibits good mechanical properties such as high tensile strength ( ca . 20 MPa) and long break elongation (>700%).
