Abstract

The crystallization behavior of Polylactide with different chain extenders and nano-clay contents were investigated using a differential scanning calorimeter (DSC). The results of As Received PLAs show that the branched structure plays the role of crystal nucleating agent. Also, the compounding process on the branched PLAs improves the crystallinity significantly due to the completion of branching reactions. The results of PLA-nanoclay show that the addition of nanoclay in different loadings does not have a significant effect on melt crystallization of half and fully branched PLAs compared with processed branched PLAs, but improve the crystallinity of linear PLA during isothermal crystallization.
