The preparation of PBAT can be divided into one step method and two step method. The traditional five-kettle one-step process, represented by Italy's Novamont company, is directly polycondensation into high molecular weight PBAT; The two-step method represented by Basf, Germany, is to first condense into low molecular weight PBAT resin, and then add chain extender to prepare high molecular weight PBAT through chain extension.
