随着单臂聚合物的臂数和相对分子质量的增加(4-5倍以上)，得到了两个系列的3-12多臂丁二烯和苯乙烯星形聚合物(S-PB和S-PS)，它们具有高的臂M-n(~gt；=20 kg mol(-1))和窄的pDi(=85%)。其中以十二臂星形PB的合成效率最高，达96.1%。利用两种不同的线型聚合物(PS-N-3和PB-N-3)与四臂核的点击反应，一锅法合成了高产率(95.1%)、高臂M-n和窄PDI(1.04)的丁二烯-苯乙烯星形共聚物。所有的星形聚合物都用GPC-MALLS-粘度-DRI进行了表征。这些多臂星形聚合物表现出从无规卷曲到硬球的形态，这取决于星形聚合物的臂数。星形PB和PS的特性粘度随臂数的增加而最大，其中PB-4Arm和PS-6arm的特性粘度最大。
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 ( = 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.
