| 中文摘要 | novel biodegradable y-shaped copolymer, poly(l-lactide)(2)-b-poly(gamma-benzyl-l-glutamic acid) (plla(2)-b-pblg), was synthesized by the ring-opening polymerization (rop) of n-carboxyanhydride of gamma-benzyl-l-glutamate (blg-nca) with centrally amino-functionalized poly(l-lactide), plla(2)-nh2, as a macroinitiator in a convenient way. the y-shaped copolymer and its precursors were characterized by h-1 nmr, ft-ir, gpc, waxd and dsc measurements. the self-assembly of the plla(2)-b-pblg copolymer in toluene and benzyl alcohol was examined. it was found that the self-assembly of the copolymer was dependent on solvent and on relative length of the pblg block. for a copolymer with plla blocks of 26 in total degree of polymerization (dp), if the pblg block was long enough (e.g., dp = 54 or more), the copolymer/toluene solution became a transparent gel at room temperature. in benzyl alcohol solution, only plla(2)-b-pblg containing ca. 190 blg residues could form a gel: those with shorter pblg blocks (e.g., dp = 54) became nano-scale fibrous aggregates and these aggregates were dispersed in benzyl alcohol homogeneously. |
