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.
