| 中文摘要 | poly(n-trityl serine lactone)(ptsl) and mpeg-block-poly(n-trityl serine lactone)(mpeg-b-ptsl, peg=polyethylene glycol) were synthesized via the ring-opening polymerization of n-trityl serine lactone(tsl) with diethyl zinc(znet2) as catalyst. the structures of these polymers were confirmed with hydrogen nuclear magnetic resonance(h-1 nmr) spectroscopy, carbon nuclear magnetic resonance(c-13 nmr) spectroscopy and infrared(ir) spectrometer. the thermal decomposition temperature and glass transition temperature of ptsl were 241 and 161 c, respectively. a series of mpeg-b-ptsl with different molecular weights(m-n's from 7000 to 32000) was obtained by tuning the tsl/mpeg feed ratio. after the removal of the trityl groups, mpeg-block-poly(serine lactone)(mpeg-b-psl) was obtained as a new kind of cationic block copolymer. low cytotoxicity of these polymers to l929 cells was confirmed via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(mtt) assay. |
