Poly(lactic acid) (PLA)/poly(butylene/dipateco- terephthalate) (PBAT) blends using/mino-ended hyperbranched polymers (HBP)/s modifiers were prepared by melt-mixing through/ double-roller mill/nd injection molding. It was found that when the content of HBP was 2.5 phr, the elongation/t break/nd the impact strength of PLA/ PBAT blends both reached peak values. Moreover, by/ddition of HBP, the.Tg of the blends was smaller. These results, together with Scanning electron microscope (SEM) images on the fractured morphology of the blends, indicate that the compatibility between PLA and PBAT is improved upon/ddition of HBP. The mechanism of the impact of HBP on the improvement of the compatibility between PLA/nd PBAT is proposed based upon Fourier transform infrared (FTIR) spectra.
