Petroleum-based engineering plastics have shown worldwide issues such as environmental threatening by their pollutions despite giving us beneficial conveniences. To this end, polylactic acid (PLA) has garnered broad attention to alter the common petroleum-based polymers. However, their inherent properties make them substantial limitations in using the PLA; for example, brittle mechanical properties limiting its applications. Herein, we have been studied for an investigation of finding the optimized conditions for the high molecular weight of PLA and its copolymers with a narrow molecular weight distribution toward the engineering approaches. In addition, the shape of PLA and its copolymers was importantly concerned for their tunable properties. To maximize their potential in using PLA-based copolymers, we designed the PLA copolymers with α-allyl ε-Caprolactone (CL) as a comonomer. The acquired PLA and its copolymers were examined for their properties in comparison.
