Study on Preparation and Structural Properties of High Toughness Polylactic Acid

摘要

Different mass ratio of polylactic acid(PLA)/maleic anhydride grafted styrene-ethylene-butadiene-styrene(SEBS-g-MAH)were prepared by melt blending and characterized by means of ATR-FTIR,SEM and mechanical properties tests.The results of investigation demonstrate: when the thermoplastic elastomer SEBS-g-MAH was added into the PLA,the two phases have certain compatibility.When adding suitable amount of SEBS-g-MAH,the toughness of the blend was remarkably improved.
