| 中文摘要 | a polymer pair composed of poly( n-isopropylacrylamide-co-2-hydroxyethyl methacrylate terminated oligo( l-lactide)) ( poly( nipaam-co-hemaolla)) graft random copolymer and poly( d-lactide) ( pdla) homopolymer was self-assembled into micelles with a diameter around 100 nm through the stereocomplexation between the olla branches of the graft copolymer and the pdla homopolymer. the specific intermolecular stereocomplexation was considered as the powerful ordered aggregation force in the micelle cores. the shell's component of poly( nipaam-co-hema) and its thermosensitivity were proved by h-1 nuclear magnetic resonance ( nmr) and dynamic light scattering ( dls), respectively. the incorporation of pdla homopolymer into the graft copolymer affected the micelle size and the critical micelle concentration ( cmc). the incorporation of even a small quantity ( 11 wt%) of pdla into the graft copolymer micelles resulted in a great decrease of the micelle size. for the graft copolymer with low per cent grafting of 18%, the size of the corresponding micelles decreased slightly even if the pdla content increased up to 33 wt%. for the graft copolymer with high per cent grafting of 58%, with the further increase of pdla content, the size of the corresponding micelles at first decreased further and then began to increase. the molecular weight of the pdla did not significantly affect the micelle size. |
