Abstract

Poly(styrene-butadiene-styrene) (SBS) copolymer was used to enhance the crystallization ability and mechanical properties of poly(L-lactic acid) (PLA) through melt mixing. The thermogravimetric analysis and Fourier transform infrared results revealed the n–π interaction between PLA and SBS. Differential scanning calorimetry and X-ray diffraction analysis indicated that the crystallization ability of the PLA improved substantially. The PLA crystallized completely during the cooling process when the SBS content in the blend was above 20 wt.%. The elongation at break and the impact resistance were significantly improved compared with that of neat PLA when the SBS content was above 50 wt.%.
