| 英文摘要 | two series of 3-12 multiarm star polymers of butadiene and styrene (s-pb and s-ps) with high m-n of arms (>= 20 kg mol(-1)) and narrow pdi (<= 1.04) were synthesized via click chemistry between azide-terminated polymers and multialkynyl organic molecules. comparing to the previous report, higher yield of coupling reaction (>= 85%) was obtained along with increasing arm number and molecular weight of the single-arm polymer (over 4-5 times that before). in particular, 96.1%, as the highest efficiency, occurred in the synthesis of 12-arm star pb. the 4-miktoarm star copolymer of butadiene and styrene was also synthesized with high yield (95.1%), high arm m-n and narrow pdi (1.04) by one pot synthesis using click reaction between two different linear polymers (ps-n-3 and pb-n-3) and a 4-arm core. all the star polymers were characterized by gpc-malls-viscosity-dri. these multiarm star polymers exhibit morphologies from random coil to hard sphere depending on the arm-number of the star polymers. intrinsic viscosity appeared the maximum with increasing arm numbers in star pb and ps, in which pb-4arm and ps-6arm had the highest values, respectively. |
