英文摘要	the inherent brittleness of poly(lactic acid) (pla) limits its wide application in many fields. here, high-impact pla/ethylene-methyl acrylate-glycidyl methacrylate random terpolymer (ema-gma) blends were prepared with the addition of a small amount of n,n-dimethylstearylamine (dmsa) catalyst. it was found that the notched impact resistance of various pla/ema-gma blends could be considerably improved by adding dmsa. in particular, the notched izod impact strength of the blend with 20 wt% ema-gma increased from 35.6 to 83.5 kj m(-2) by adding 0.2 wt% dmsa. reactive compatibilization between pla and ema-gma with dmsa was studied using fourier transform infrared spectroscopy. the results indicated that dmsa promoted the reaction between the epoxide group of ema-gma and end groups (-oh, -cooh) of pla. this considerably improved the interfacial adhesion, leading to better wetting of the dispersed phase by the pla matrix and finer dispersed ema-gma particles. therefore, the significant increase in notched impact strength was attributed to the effective reactive compatibilization promoted by dmsa.
