Tapered (cone-shaped) bottlebrush polymers were synthesized for the first time by ring-opening metathesis polymerization (ROMP) using a sequential-addition of macromonomers (SAM) strategy. Polystyrene macromonomers with molecular weights that increased from 1 to 10 kg mol were polymerized in sequence to high conversion, yielding tapered bottlebrush polymers that could be visualized by atomic force microscopy (AFM).
首次通过开环易位聚合（ROMP），采用大分子单体顺序添加（SAM）策略合成了锥形（圆锥状）瓶刷聚合物。分子量从1增至10 kg/mol的聚苯乙烯大分子单体依次聚合至高转化率，得到了可用原子力显微镜（AFM）观察到的锥形瓶刷聚合物。
