摘要

Abstract

Miscibility

isothermal crystallization kinetics

and morphology of poly(L-lactide)/poly(trimethylene carbonate) (PLLA/PTMC) crystalline/amorphous blends were studied by differential scanning calorimetry (DSC) and optical microscopy (OM). The heterogeneity of OM images and an unchanged glass transition temperature showed that PLLA was immiscible with PTMC. During isothermal crystallization

the crystallization rate of PLLA improved when the PTMC content was low (≤ 20%). However

when the PTMC content was high (≥ 30%)

the crystallization rate decreased significantly. The reason of these nonlinear changes in crystal kinetics was analyzed according to the nucleation and growth process by virtue of a microscope heating stage. The isothermal crystallization morphologies of the blends were also studied by polarized optical microscopy and the results confirmed the conclusions obtained from crystallization kinetics.
