摘要

Poly(lactic acid)(PLA)and starch are important biodegradable polymers. Mechanical properties of blends of PLA and starch using conventional processes were very poor because of incompatibility. In this study, PLA and starch were blend with a reactive agent during the extrusion process. The Affects of the reactive blending were investigated and significant improvements were confirmed by Measuring the tensile strength and elongation at break, IR spectra, and DSC.
