中文摘要	poly(d,l-lactide) (pdlla) and stereocomplex-poly (l- and d-lactide) (sc-pla) blends were prepared by solution blending. the influence of the addition of pdlla on nonisothermal crystallization behavior of sc-pla was investigated. it was observed that the crystallization peak temperature of pdlla/sc-pla blends was marginally lower than that of neat sc-pla at various cooling rates. furthermore, the half-time for crystallization increased with an increase in pdlla content, indicating the dilution effect of pdlla on the sc-pla component to restraint the overall crystallization process. the nonisothermal crystallization data was analyzed using avrami, ozawa and combined ozawa-avrami models methods. the validity of kinetic models on the nonisothermal crystallization process of neat sc-pla and pdlla/sc-pla blends was discussed. the approach developed by combined ozawa-avrami models successfully described the nonisothermal crystallization behavior of neat sc-pla and pdlla/sc-pla blends. the activation energy for nonisothermal crystallization of neat sc-pla and pdlla/sc-pla blends based on friedman equation was evaluated.
