| Abstract: | Stretching of amorphous polylactide above glass transition temperature can lead to strain‐induced crystallization, which is mainly determined by stretching rate and temperature. This study demonstrates that thermal annealing prior to stretching is alternative to enhance strain‐induced crystallization of a given polylactide at the identical stretching conditions. The local order generated during thermal annealing acts as physical crosslinks to effectively alleviate molecular relaxation and thus facilitates the advent of strain‐induced crystallization. © 2013 Wiley Periodicals, Inc.
