| 中文摘要 | the confined crystallization behavior, melting behavior, and nonisothermal crystallization kinetics of the poly(ethylene glycol) block (peg) in poly(l-lactide)poly(ethylene glycol) (plla-peg) diblock copolymers were investigated with wideangle x-ray diffraction and differential scanning calorimetry. the analysis showed that the nonisothermal crystallization behavior changed from fitting the ozawa equation and the avrami equation modified by jeziorny to deviating from them with the molecular weight of the poly(l-lactide) (plla) block increasing. this resulted from the gradual strengthening of the confined effect, which was imposed by the crystallization of the plla block. the nucleation mechanism of the peg block of plla15000-peg5000 at a larger degree of supercooling was different from that of plla2500-peg5000, plla5000-peg5000, and peg5000 (the numbers after peg and plla denote the molecular weights of the peg and plla blocks, respectively). they were homogeneous nucleation and heterogeneous nucleation, respectively. |
