英文摘要	stereocomplex-poly(l- and d-lactide) (sc-pla) and poly(methyl methacrylate) (pmma) blends were prepared by solution blending at pmma loadings from 20 to 80 mass%. the miscibility and crystallization behaviors of the blends have been studied in detail by differential scanning calorimeter. the single-glass transition temperatures (t (g)) of the blends demonstrated that the obtained system was miscible in the amorphous state. it was observed that the crystallization peak temperature of sc-pla/pmma blends was marginally lower than that of neat sc-pla at various cooling rates, indicating the dilution effect of pmma on the sc-pla component to restrain the overall crystallization process. in the study of isothermal crystallization kinetics, the reciprocal value of crystallization peak time () decreased with increasing pmma content, indicating that the addition of non-crystalline pmma inhibited the isothermal crystallization of sc-pla at an identical crystallization temperature (t (c)). moreover, the negative value of flory-huggins interaction parameter (chi (12) = -0.16) of the blend further indicated that sc-pla and pmma formed miscible blends.
