| 中文摘要 | the micelle formation of a series of amphiphilic block copolymers in aqueous and nacl solutions was studied by a fluorescent probe technique using pyrene as a 'model drug'. these copolymers were synthesized from poly (ethylene glycol) (peg) and l-lactide by a new calcium ammoniate catalyst. they had fixed peg block lengths (44, 104 or 113 ethylene oxide units) and various poly(l-lactide) (plla) block lengths (15-280 lactide units). the critical micelle concentration (cmc) was found to decrease with increasing plla content. the distinct dissimilarity of the cmc values of diblock and triblock copolymers based on the same block length of peg provided evidence for the different configurations of their micelles. it was also observed that the introduction of nacl salt significantly contributed to a decrease in the cmcs of the copolymers with short peg and plla blocks, while it had less influence on the cmcs of copolymers with long peg or plla blocks. the dependence of partition coefficients ranging from 0.2x10(5) to 1.9x10(5) on the plla content in the copolymer and on the micelle configuration was also discussed. |
