Reported herein is the impact of glycidol-free chain extenders on poly(lactic acid) (PLA) to enhance its mechanical properties. Gel permeation chromatography characterization confirmed the molecular weight (M w ) of the chain extenders as well as the chain-extended PLA samples. Tensile properties, such as elongation, modulus, and impact strength, were evaluated for the chainextended PLA and compared with those of a commercial chain extender. Thermal characteristics of the chain-extended PLA were measured by using thermogravimetric analysis and differential scanning calorimetry. The complex viscosity and storage modulus for chain-extended PLA were also determined. Cost analysis and CO 2 emission estimates are conducted for the new chain extenders and are compared with commercial chain extenders. Overall, chain extenders are likely to offer economic, health, and environmental benefits.
