Abstract
The crystallization and melting behaviors of polylactide (PLA) homochiral polymer under the confinement of stereocomplex crystallites were studied in the linear and three-armed poly(d-lactide)/poly(l-lactide) (PDLA/PLLA and 3PDLA/3PLLA) solution casting blends. WAXD results showed that novel modified crystallites formed when PLA homopolymer crystallized from the melting state. And the modified crystallites formed in 3PDLA/3PLLA blends (M-A) were less stable than that formed in similar PDLA/PLLA blends (M-B) after specimens cooled at a specific rate. Although these modified crystallites differed from PLA α crystallites (M-C), both of them transformed into α crystallites during heating. The transitions among different crystallites revealed the multiple melting behaviors in DSC measurement. The type of PLA homochiral crystallites and their contents mainly depended on the D/L compositions, annealing conditions, molecular weights, and architectures of the polymers in the blends. The formation of these modified...
